BME680 Environmental Sensor

£39.66 £33.05

The Bosch Sensortec BME680 Integrated Environmental Unit combines a gas sensor with air pressure, humidity, and ambient air temperature sensing functions within a single package for high performance air quality measurement.


Parallax Inc. places the BME680 on a compact PCB with a 6-pin male header.

This capable sensor does not have to be difficult to use. The BME680 is supported by BlocklyProp visual programming as well as C libraries for the Propeller multicore microcontroller.  Code for other controllers is available from the Bosch Github repository.


  • Low power, high-performance gas, pressure, temperature, and relative humidity sensor in a single package
  • Detects a broad range of VOCs (Volatile Organic Compounds)
  • Supports I2C, SPI 3-wire, and SPI 4-wire interfaces
  • Overvoltage, reverse polarity and signal contention protection of all signal pins
  • VIN / GND reverse polarity protection
  • Compatible with 3.3 V and 5 V microcontrollers
  • Breadboard-friendly 6-pin header with 0.1” spacing, plus two mounting holes
