Enviro+ for Raspberry Pi (enviro+ sensor phat)

Monitor your world with Enviro+ for Raspberry Pi! There's a whole bunch of fancy environmental sensors on this board, and a gorgeous little full-colour LCD to display your data. It's the perfect way to get started with citizen science!

Designed for environmental monitoring, Enviro+ lets you measure air quality (pollutant gases and particulates*), temperature, pressure, humidity, light, and noise level. When combined with a particulate matter sensor*, it's great for monitoring air quality just outside your house (more information below), or without the particulate sensor you can use it to monitor indoor conditions.

Enviro+ is an affordable alternative to environmental monitoring stations that can cost tens of thousands of pounds and, best of all, it's small and hackable and lets you contribute your data to citizen science efforts to monitor air quality via projects like Luftdaten.

Features

  • BME280 temperature, pressure, humidity sensor (datasheet)
  • LTR-559 light and proximity sensor (datasheet)
  • MICS6814 analog gas sensor (datasheet)
  • ADS1015 analog to digital converter (ADC) (datasheet)
  • MEMS microphone (datasheet)
  • 0.96" colour LCD (160x80)
  • Connector only for particulate matter (PM) sensor*(sensor is not included)
  • pHAT-format board
  • Fully-assembled
  • Compatible with all 40-pin header Raspberry Pi models
  • Pinout
  • Python library
  • Dimensions: 65x30x8.5mm

A couple of nice little extras... there's a spare ADC channel broken out on a header if you want to connect another analog sensor, along with I2C pins in the right configuration for plugging one of our Pimoroni I2C breakouts onto!

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.

Adafruit 9-DOF Accel/Mag/Gyro+Temp Breakout Board - LSM9DS1 (Adafruit 9-DOF Accel)

Inside the chip are three sensors, one is a classic 3-axis accelerometer, which can tell you which direction is down towards the Earth (by measuring gravity) or how fast the board is accelerating in 3D space. The other is a 3-axis magnetometer that can sense where the strongest magnetic force is coming from, generally used to detect magnetic north. The third is a 3-axis gyroscope that can measure spin and twist. By combining this data you can REALLY orient yourself.

Design your own activity or motion tracker with all the data... Adafruit spun up a breakout board that has all the extra circuitry you'll want, for use with an Arduino (or other microcontroller).

The LSM9DS1 is not the same set of sensors as the LSM9DS0. Here are some of the differences:

  • LSM9DS0 accelerometer has ±2/±4/±6/±8/±16 g ranges. The LSM9DS1 has ±2/±4/±8/±16 g (no ±6 g range).
  • LSM9DS0 magnetometer has ±2/±4/±8/±12 gauss ranges. The LSM9DS1 has ±4/±8/±12/±16 gauss ranges. So the LSM9DS0 has ±2 gauss low range where-as the LSM9DS1 has ±16 gauss high range.
  • LSM9DS0 and LSM9DS1 gyros both have the same ±245/±500/±2000 dps ranges.

There are other differences, for example we noticed the LSM9DS1 has slightly worse accuracy. The gyro angular zero-rate (±25 for the LSM9DS0 and ±30 for the LSM9DS1 at the highest sensing range). The accelerometer offset accuracy is ±90 mg for the LSM9DS1 and ±60 mg for the LSM9DS0.

However, these offsets may not matter for most projects and the pricing of the LSM9DS1 is lower than the LSM9DS0.

The breakout board version of this sensor has both I2C and SPI interfaces. Attaching it to the Arduino is simple, power Vin and GND with 3-5VDC, and wire up I2C data on SCL and SDA, and you're ready to go! More advanced users can use SPI, the library has support for both. The breakout comes fully assembled and tested, with some extra header so you can use it on a breadboard. Four mounting holes make for a secure connection, and Adafruit put the popular power+data pins on one side, and the interrupt pins on the other side for a nice & compact breakout.

This tutorial will get you started with wiring diagrams, pinouts, assembly instructions and library code with examples!

Waterproof DS18B20 Digital temperature sensor + Resistor 1M (Waterproof DS18B20 temp)

Description:

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.

Specifications:

Cable specs:

  • Stainless steel tube 6mm diameter by 30mm long
  • Cable is 36" long / 91cm, 4mm diameter
  • Contains DS18B20 temperature sensor
  • If  your sensor has four wires - Red connects to 3-5V, Black connects to  ground and White is data. The copper wire is soldered to the wire  shielding
  • If your sensor has three wires - Red connects to 3-5V, Blue/Black connects to ground and Yellow/White is data

DS18B20 Technical specs:

  • Usable temperature range: -55 to 125°C (-67°F to +257°F)
  • 9 to 12 bit selectable resolution
  • Uses 1-Wire interface- requires only one digital pin for communication
  • Unique 64 bit ID burned into chip
  • Multiple sensors can share one pin
  • ±0.5°C Accuracy from -10°C to +85°C
  • Temperature-limit alarm system
  • Query time is less than 750ms
