BOSCH BME 680 - Combo sensor, air pressure/humidity/temp./gas

BME680 is an integrated environmental sensor developed specifically for mobile applications and wearables where size and low power consumption are key requirements. Expanding Bosch Sensortec’s existing family of environmental sensors, the BME680 integrates for the first time high-linearity and high-accuracy gas, pressure, humidity and temperature sensors. It consists of an 8-pin metal-lid 3.0 x 3.0 x 0.93 mm³ LGA package which is designed for optimized consumption depending on the specific operating mode, long term stability and high EMC robustness. The gas sensor within the BME680 can detect a broad range of gases to measure indoor air quality for personal well being.
