With the BME680, Bosch Sensortec is launching what it claims to be the market's first gas sensor with sensors for air pressure, humidity and ambient temperature in a housing with a footprint of 3 mm x 3 mm. The sensor enables functions for mobile devices such as air quality measurement, personalized weather stations, indoor navigation, fitness trackers, home automation and other applications for the Internet of Things. To measure indoor air quality for personal well-being, the gas sensor detects a wide range of gases including volatile organic compounds (VOCs) from paints (such as formaldehyde), varnishes, solvents, cleaning agents, furnishings, office equipment, glues, adhesives and alcohol. By combining four sensors in one housing, the environmental sensor provides accurate, detailed data of the real world. The sensor's pressure accuracy of ±0.12 Pa provides precise height information down to ±1 m. The offset temperature coefficient of 1.5 Pa/K enables a temperature-related height deviation of 12.6 cm/K. The sensor is equipped with both I2C and SPI communication interfaces. The sensor is housed in an LGA housing with a metal cover.
