Environment click measures temperature, relative humidity, pressure and VOC (Volatile Organic compounds gases). The click carries the BME680 environmental sensor from Bosch. Environment click is designed to run on a 3.3V power supply. It communicates with the target microcontroller over SPI or I2C interface. You can use it to test your indoor air quality, to control HVAC (heating, ventilation, and air conditioning) systems, in a weather station, sports applications and more.
