Tiny MEMS device integrates gas sensor delivering superior environmental measurement performance

Mouser now offers the BME680 environmental sensor from Bosch Sensortec. The sensor delivers superior environmental measurement performance, made possible by the internal compensation and calibration of gas, pressure, temperature and humidity sensors. The sensor enables new capabilities for mobile devices such as air quality measurement, personalized weather stations, indoor navigation, fitness monitoring, home automation and other IoT applications. The sensor is a tiny, low-power microelectromechanical system (MEMS) device that integrates a gas sensor with air pressure, humidity and ambient air temperature sensing functions. The gas sensor can detect a broad range of gases in order to measure indoor air quality, including VOC — from sources such as paints, cleaning supplies, furnishings, and adhesives — down to the parts-per-million range. The device’s pressure accuracy provides precise altitude information. The fast response time for measurement of humidity and ambient temperature enables new applications, such as personalized weather information and air quality monitoring. The sensor is equipped with both I2C and SPI communication interfaces, as well as three power modes and oversampling rates for pressure and temperature measurements that can be configured separately to help designers easily adapt it to different applications. An integrated IIR filter eliminates short-term measurement fluctuations caused by potential environmental influences.
