Waterproof DS18B20 Digital temperature sensor + Resistor (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:

  • 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)

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.

SONOFF SNZB-02 ZigBee Temperature And Humidity Sensor Real Time Low-battery notification Works with SONOFF ZigBee Bridge eWeLink APP (zigbee SNZB-02)

Note 1: Batteries not included - ( 3V CR2450)
Note 2: SNZB-02 must be used with the Zigbee Bridge.

SONOFF SNZB-02 is a ZigBee temperature and humidity sensor that can seamlessly work with SONOFF ZigBee Bridge to track and record the temperature and humidity change in your home, which all real-time readings can be checked on eWeLink APP. Better still, you can set a condition in the smart scene that is the fan is turn on/off when the temperature reaches the limit value, or the dehumidifier in your room starts working once the humidity is over higher, helping prevent the growth of mildew and allergens. You can set a smart scene to trigger alerts through events like high/low temperature, high/low humidity conditions and more.

Device sharing function makes your kids, family, and even the neighbors informed about the environmental conditions of your home with their mobile phones.

It is a battery-operated sensor that can be placed in any corner of your house to monitor the room temperature and humidity. Installation without any tool, simply stick the sensor on the surface of the wall or device and see it nicely to work for you!

Grove - Temperature Sensor (Grove temp sensor)

Grove - Temperature Sensor uses a thermistor to measure ambient temperature. The resistance of thermistor changes based on ambient temperature. This resistance value alters the output of a voltage divider which is measured by an analog input pin and converted to a temperature value. The operating range is -40 to 125°C , with an accuracy of 1.5°C.

For all Grove users (especially beginners), we provide you guidance PDF documents. Please download and read through Preface - Getting Started and Introduction to Grove before your use of the product.

Ready to use with microcontrollers as a digital input. This product also has a compact modular design Plug-and-play grove compatible interface.

Based on the picture above, the grove shield for Arduino is stacked with Seeeduino V4.2. Of course you can use that shield with Arduino board too :)

You can get grove HAT for Raspberry Pi and the Maker Pico board
