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.

Features:

  • 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

Application Ideas:

  • Air quality monitoring
  • Home automation and control
  • Weather forecast
  • Warning system for high temp, low-humidity conditions
  • Context awareness, e.g. skin moisture detection, room change detection
  • Vertical velocity indicator (rise/sink speed)
  • Indoor navigation, e.g. change of floor detection, elevator detection
  • Altitude tracking and calories expenditure for sports activities
