Waterproof DS18B20 Digital temperature sensor Resistor (Waterproof DS18B20 temp)
This is a pre-wired and waterproofed version of the DS18B20 sensor.  Handy for when you need to measure something far away, or in wet  conditions. While the sensor is good up to 125°C the cable is jacketed  in PVC so we suggest keeping it under 100°C. Because they are digital,  you don't get any signal degradation even over long distances! These  1-wire digital temperature sensors are fairly precise (±0.5°C over much  of the range) and can give up to 12 bits of precision from the onboard  digital-to-analog converter. They work great with any microcontroller  using a single digital pin, and you can even connect multiple ones to  the same pin, each one has a unique 64-bit ID burned in at the factory  to differentiate them. Usable with 3.0-5.0V systems.

The only  downside is they use the Dallas 1-Wire protocol, which is somewhat  complex, and requires a bunch of code to parse out the communication. If  you want something really simple, and you have an analog input pin,  the TMP36 is trivial to get going.

We toss in a 4.7k resistor, which is required as a pullup from the DATA to VCC line when using the sensor.

Wind and Rain Sensors for Weather Station (Wind Vane / Anemometer / Rain Gauge) (Weather wind/rain kit)

Want to build your own weather station? This sensor kit has a cup anemometer and wind vane to measure wind speed and direction and a tipping bucket style rain gauge, together with associated mounting hardware.

The sensors in this kit are active mechanical sensors that work by physically interacting with the wind and rain. They use magnets, reed switches and moving parts to produce simple signals that a microcontroller or single board computer can use to calculate wind speed, wind direction and rainfall.

The sensor cables are terminated in RJ11 connectors (each sensor only uses two wires though, so if you wanted you could snip off the ends and connect the wires to a different kind of connector). Armatures to mount the sensors are included, as well as a short metal mast that can be lashed to the top of a suitable pole with the included jubilee connectors.

Please note that this kit contains the mechanical wind and rain sensors only, and doesn't include any electronic components. You'll likely want to hook these sensors up to something like a Weather HAT (for Raspberry Pi), a weather:bit (for micro:bit) or a Weather Shield (for Arduino).

What's in the box?

  • Wind vane
  • Anemometer
  • Rain gauge
  • Short metal mast (made of two metal poles that slot together)
  • Two plastic arms for mounting the sensors
  • Mounting hardware: jubilee clips, nuts, bolts and cable ties

Weather HAT (HAT only) (PM weather hat)

A meteorologically minded Raspberry Pi HAT designed to make hooking up weather sensors a breeze (or a squall, or a gale).

Weather HAT is a tidy all-in-one solution for hooking up climate and environmental sensors to a Raspberry Pi. It has a bright 1.54" LCD screen and four buttons for inputs. The onboard sensors can measure temperature, humidity, pressure and light. The sturdy RJ11 connectors (remember those?) will let you easily attach wind and rain sensors. It will work with any Raspberry Pi with a 40 pin header (that's most of them except the really old ones).

You could install it outside in a suitable weatherproof enclosure (like a waterproof junction box or even a Tupperware container) and connect to it wirelessly - logging the data locally or piping it into Weather Underground, a MQTT broker or a cloud service like Adafruit IO. Alternatively, you could house your weather Pi inside and run wires to your weather sensors outside - making use of the nice screen to display readouts.

Please note: the wind and rain sensors are sold separately.

Features

  • 1.54" IPS LCD screen (240 x 240)
  • Four user-controllable switches
  • BME280 temperature, pressure, humidity sensor (datasheet)
  • LTR-559 light and proximity sensor (datasheet)

Software

We've put together a Python library to give you easy access to all Weather HAT's functions, together with straightforward examples to help you learn how to read the sensors and use all the individual parts. There's also a weather station example that shows you how it's possible to combine all the functions into an application.

Our Getting Started tutorial contains a thorough walkthrough of Weather HAT's functionality plus beginner friendly instructions for installing the Python library and running the examples.

Notes

  • Want to add on more I2C sensors? No problem, there's an solderless I2C header located on the back of the HAT that you can poke jumper / DuPont wires in to.
  • If you'd like to hook up more analog sensors (3.3v max) we've broken out some extra ADC channels on the front of the board, as well as a convenient 3v3 power and ground.
  • We've found two standoffs at the GPIO edge to be sufficient to keep this HAT firmly in place, but if you're attaching it to a full-size Pi and want to add standoffs at every corner you can pick up some more.

Enviro Indoor (Pico W Aboard) with accessories (Enviro indoor kit)

A wireless environmental monitoring board to keep track of inside conditions in your home, office or other habitat. Onboard sensors can measure temperature, humidity, pressure, gas and light.

The top of the range BME688 sensor on Enviro Indoor can measure temperature/humidity/pressure with a high degree of precision, and the gas scanner will react to changes in volatile organic compounds (VOCs), volatile sulfur compounds (VSCs) and the presence of carbon monoxide and hydrogen to give a general measure of air quality. The BH1745 light sensor can tell you the luminance and colour of light, so you could use it to detect unrestful blue light or adjust your lighting's intensity/hue depending on the time of day.

Want to add more sensors to this board? A CO2 sensor breakout (plugged into the Qw/ST connector) would make a nice addition, so you could keep an eye on ventilation levels and cognition impairing carbon dioxide build-up.

Enviro x Pico W Aboard

Our new Enviro (Pico W Aboard) range is designed with environmental monitoring / logging in mind. We wanted to make a range of Pico/RP2040-powered, all-in-one sensor boards that are compact, easy to install in places and straightforward to program. The wireless capability of Raspberry Pi Pico W lets Enviro integrate with other systems - so you could post your data into databases, home automation systems, or online citizen science efforts - the Internet's your lobster!

Because the least fun thing about adding lots of sensors to your environment is figuring out how supply power to everything without tons of trailing wires, they are all designed to work well off battery power.  Each Enviro board has an onboard RTC (Real Time Clock), so that they can periodically wake up from deep sleep, take a reading (and, optionally, connect to wifi) and then go back to sleep - giving you months of untethered battery life.

We've also put together some handy accessory kits to go with our Enviro boards, that include an appropriately sized AA or AAA battery pack, a USB cable and other essentials for each board, so you can get going super quick.

Enviro Features

  • Raspberry Pi Pico W Aboard
    • Dual Arm Cortex M0+ running at up to 133Mhz with 264kB of SRAM
    • 2MB of QSPI flash supporting XiP
    • Powered and programmable by USB micro-B
    • 2.4GHz wireless
  • Deep sleep/wake function using RTC
  • 1 x POKE (user) button
  • Reset button (because we're not monsters)
  • Battery connector (JST-PH connector, 5.5V max voltage)
  • User/activity LED (dimmable via PWM, can only be lit when board is awake)
  • Warn LED (attached to RTC)
  • Qw/ST connector for attaching breakouts
  • Fully assembled
  • No soldering required.
  • Enviro firmware
  • Schematic

Enviro Indoor Features

  • BME688 4-in-1 temperature, pressure, humidity and gas sensor (datasheet)
  • BH1745 light (luminance and colour) sensor (datasheet)

Software

Enviro ships with some super slick provisioning software that makes it really easy to set it up and connect to things, even if it's your first foray into environmental logging/IoT. Power it up and connect to the network called 'Enviro Indoor Setup' with your phone, tablet or other wi-fi enabled device - your Pico W will walk you through the rest!


Connecting Breakouts

The Qw/ST connectors on Enviro boards make it super easy to connect up I2C Qwiic or STEMMA QT breakouts. If your breakout has a QW/ST connector on board, you can plug it straight in with a JST-SH to JST-SH cable. 

Breakout Garden breakouts that don't have a Qw/ST connector can be connected using a JST-SH to JST-SH cable plus a Qw/ST to Breakout Garden adaptor.

Notes

  • Measurements: 69 x 36 x 9.9 mm (L x W x H, approx)
  • Enviro boards can enter a deep sleep mode where the Pico W, on board sensors and sensors connected via Qw/ST are completely powered down. The only thing left running on the board is the RTC which can wake up the board again at a set date and time or on a timer. You can also wake up the board via the POKE button, or by connecting the USB cable (the board will never sleep if connected to USB power).
  • The RTC can also be used to keep track of the time and date (which means we don't need to waste power by making a wireless call to find out the time/date each time we log a sensor reading!)
  • The Warn LED is connected to the RTC, so it can be lit even during deep sleep to notify you of problems. It is limited to three states - on, off, or 1hz blink (it's not possible to control the brightness).
  • Most Enviro boards can be powered by a 2 x AAA battery pack, which fits neatly behind the board. Any battery pack that can supply between 2V and 5.5V will work though - 2 or 3 alkaline AA or AAA cells, 4 rechargeable NiMH cells or a single cell LiPo. If you're using a LiPo, bear in mind there's no battery charging included on Enviro boards, so you'll need a separate LiPo battery charger (like a LiPo Amigo) to be able to charge it.

About Pico W Aboard

Our new Pico W Aboard products come with a built in Raspberry Pi Pico W. This means you get all the advantages of a RP2040 microcontroller - a speedy fast dual-core ARM processor, a dynamic, growing ecosystem and a choice of different programming methods to experiment with. Most excitingly though, Pico W has wireless connectivity, so your Pico/RP2040 devices can communicate with each other, and the internet!

Citizen science air quality monitoring

We've developed this board in collaboration with the University of Sheffield, with the aim of letting you contribute real-time air quality data from your local area to open data projects like Luftdaten.

The alarming drop in our air quality is something that's really important to understand. Devices like Enviro  allow fine-grained, detailed datasets that let us see shifts in air quality through time and across different areas of cities. The more devices that contribute data, the better quality the dataset becomes.

Particulate matter (PM) is made up of tiny particles that are a mix of sizes and types, like dust, pollen, mould spores, smoke particles, organic particles and metal ions, and more. Particulates are much of what we think of as air pollution. They can be measured, in size and quantity, by particulate matter sensors like the PMS5003 that you can connect to Enviro .

The analog gas sensor can be used to make qualitative measurements of changes in gas concentrations, so you can tell broadly if the three groups of gases are increasing or decreasing in abundance. Without laboratory conditions or calibration, you won't be able to say "the concentration of carbon monoxide is n parts per million", for example.

Temperature, air pressure and humidity can all affect particulate levels (and the gas sensor readings) too, so the BME280 sensor on Enviro  is really important to understanding the other data that Enviro outputs.

We've got a tutorial (coming soon) that shows you how to use Enviro  and a few easily-available bits to build the board into a weather-proof housing that you can mount outside your house to monitor local air quality.

Indoor monitoring

As well as outdoor air quality monitoring, Enviro  is really good for indoor monitoring too. The temperature, humidity, light, and noise readings can be used to keep track of conditions in your home and, combined with the LCD to display the data and the proximity sensor for interaction, it makes an ideal headless monitoring device.

Why not combine it with some IoT smarts like an Alexa skill so that you can ask what the temperature or humidity is? Or you could set up a trigger action with IFTTT that turns your Philips Hue lights on when the light level drops below a certain level. There's loads of possibilities!

Software

We've put together a Python library to control all the parts of your Enviro . There's a bunch of examples for each of the individual parts, an all-in-one example that shows you the data from Enviro 's sensors in a visual way. There's also an example that shows you how to contribute data to Luftdaten (requires particulate matter sensor).

Getting started

Have a read through our (exhaustive!) Getting Started with Enviro  tutorial that walks you through how to install the software, how to run the code examples, and how to use the Enviro  Python library.

Enviro Weather (Pico W Aboard) - Board Only (Enviro weather board)

A wireless climate and environmental monitoring system designed to make hooking up weather sensors a breeze (or a squall, or a gale).

Enviro Weather is a super slimline all in one board for keeping a (weather) eye on the great outdoors. The onboard sensors can measure temperature, humidity, pressure and light. The sturdy RJ11 connectors (remember those?) will let you easily attach wind and rain sensorsWe've designed this one to be installed outside in a suitable weatherproof enclosure (like a Stevenson screen) and connected to wirelessly - logging the data locally or piping it into databases, home automation dashboards or online citizen science projects.

Please note wind and rain sensors are sold separately.

Enviro x Pico W Aboard

Our new Enviro (Pico W Aboard) range is designed with environmental monitoring / logging in mind. We wanted to make a range of Pico/RP2040-powered, all-in-one sensor boards that are compact, easy to install in places and straightforward to program. The wireless capability of Raspberry Pi Pico W lets Enviro integrate with other systems - so you could post your data into databases, home automation systems, or online citizen science efforts - the Internet's your lobster!

Because the least fun thing about adding lots of sensors to your environment is figuring out how supply power to everything without tons of trailing wires, they are all designed to work well off battery power.  Each Enviro board has an onboard RTC (Real Time Clock), so that they can periodically wake up from deep sleep, take a reading (and, optionally, connect to wifi) and then go back to sleep - giving you months of untethered battery life.

We've also put together some handy accessory kits to go with our Enviro boards, that include an appropriately sized AA or AAA battery pack, a USB cable and other essentials for each board, so you can get going super quick.

Enviro Weather Features

  • BME280 temperature, pressure, humidity sensor (datasheet)
  • LTR-559 light and proximity sensor (datasheet)
  • RJ11 connectors for connecting wind and rain sensors

Software

Enviro ships with some super slick provisioning software that makes it really easy to set it up and connect to things, even if it's your first foray into environmental logging/IoT. Power it up and connect to the network called 'Enviro Weather Setup' with your phone, tablet or other wi-fi enabled device - your Pico W will walk you through the rest!

Connecting Breakouts

The Qw/ST connectors on Enviro boards make it super easy to connect up I2C Qwiic or STEMMA QT breakouts. If your breakout has a QW/ST connector on board, you can plug it straight in with a JST-SH to JST-SH cable. 

Breakout Garden breakouts that don't have a Qw/ST connector can be connected using a JST-SH to JST-SH cable plus a Qw/ST to Breakout Garden adaptor.

Notes

  • Measurements: 69 x 36 x 14 mm (L x W x H, approx)
  • Enviro boards can enter a deep sleep mode where the Pico W, on board sensors and sensors connected via Qw/ST are completely powered down. The only thing left running on the board is the RTC which can wake up the board again at a set date and time or on a timer. You can also wake up the board via the POKE button, or by connecting the USB cable (the board will never sleep if connected to USB power). Power consumption when asleep is 20uA.
  • The RTC can also be used to keep track of the time and date (which means we don't need to waste power by making a wireless call to find out the time/date each time we log a sensor reading!)
  • The Warn LED is connected to the RTC, so it can be lit even during deep sleep to notify you of problems. It is limited to three states - on, off, or 1hz blink (it's not possible to control the brightness).
  • Most Enviro boards can be powered by a 2 x AAA battery pack, which fits neatly behind the board. Any battery pack that can supply between 2V and 5.5V will work though - 2 or 3 alkaline AA or AAA cells, 4 rechargeable NiMH cells or a single cell LiPo. If you're using a LiPo, bear in mind there's no battery charging included on Enviro boards, so you'll need a separate LiPo battery charger (like a LiPo Amigo) to be able to charge it.

About Pico W Aboard

Our new Pico W Aboard products come with a built in Raspberry Pi Pico W. This means you get all the advantages of a RP2040 microcontroller - a speedy fast dual-core ARM processor, a dynamic, growing ecosystem and a choice of different programming methods to experiment with. Most excitingly though, Pico W has wireless connectivity, so your Pico/RP2040 devices can communicate with each other, and the internet!
