BME680 Environmental Sensor, 28061
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.
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
