BME688 4-IN-1 QUALITY BREAKOUT(GAS TEMPERATURE,PRESSURE, HUMIDITY))

Add to wishlist

Features

Kit includes

  • BME688 breakout
  • 1×5 male header
  • 1×5 female right angle header

We’ve designed this breakout board so that you can solder on the piece of right angle female header and pop it straight onto the bottom left 5 pins on your Raspberry Pi’s GPIO header (pins 1, 3, 5, 7, 9). The right angle header also has the advantage of positioning the breakout away from the Pi’s CPU so as to minimise radiated heat.

Software

Bosch provide a C library,for this sensor, but we’ve also updated our BME680?Python library?(with a quick and painless one-line-installer) to work with the BME688, making it straightforward to combine it with our other boards (why not use a Blinkt! or Unicorn pHAT to visualise air quality in real time?)

You can also use this breakout with Raspberry Pi Pico and other?RP2040 boards,?using?C++?or Pirate brand MicroPython.

Notes

  • In our testing, we’ve found that the sensor requires some burn-in time (at least 20 minutes) and that readings may take a couple of minutes to stabilise after beginning measurements
  • The trace on the back of the board marked ADDR can be cut to change the I2C address from the default of 0x76 to 0x77, meaning that you can use up to two sensors on the same Raspberry Pi or Arduino
  • The BME280, BME680, BMP280 and BME688 breakouts all share the same I2C addresses, so if you’re using two together then you’ll need to change the I2C address on one of them using the solder bridge or cuttable traces.
  • Dimensions: approx 19mm x 19mm x 5mm (L x W x H, including connector)

The super-smart BME688 air quality sensor can measure temperature, pressure and humidity precisely. It also has an upgraded, AI-enhanced gas scanner!

Like its predecessor the BME680, this high quality sensor can be used to monitor every aspect of your environment, taking high precision measurements of?temperature, pressure and humidity.

Additionally, the BME688 has an?updated gas scanner?function?with extended measurements, which 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 indoor or outdoor air quality. With?Bosch’s software, you can analyse the gas readings further and train the algorithms to make inferences about specific air quality indicators, including the likelihood of bacteria growth and the presence of other organic contaminants.

Want to get an idea of whether there’s adequate ventilation in your bedroom, your workshop, or workplace? Set up a BME688 on a Pi Zero W and have it log sensor readings to a file or post them into your home automation software or a web service like?adafruit.io?or?freeboard.io.

This breakout is compatible with our fancy?Breakout Garden?system, where using breakouts is as easy just popping it into one of the slots and starting to grow your project, create, and code.?It’s?also?Qw/ST compatible?so?it can be plugged into a whole range of different?microcontrollers and HATs?with Qwiic or STEMMA QT connectors.
