Sensor combines pressure, humidity and temperature measurement
Bosch Sensortec announced the BME280 Integrated Environmental Unit, which combines sensors for pressure, humidity and temperature in a single package. This sensor has been developed to support a broad range of emerging high performance applications such as indoor navigation, home automation control, personalized weather stations and innovative sport and fitness applications. The sensor’s precise altitude measurement function is a key requirement in applications such as indoor navigation with floor tracking where exceptional accuracy, low temperature drift and high resolution are needed. Additionally, the BME280 has a best-in-class response time of just one second for humidity determination, excellent ambient temperature measurement and low energy consumption. With a small footprint of 2.5 x 2.5 mm2 and a height of 0.93 mm in an 8-pin LGA package, the sensor offers high design flexibility and is suited for mobile devices with limited space such as smartphones, tablets, smart watches and electronic wristbands. Very low current consumption of only 3.6 µA (at 1 Hz) makes the BME280 Integrated Environmental Unit suitable for battery-driven applications. Three power modes and separately configurable oversampling rates for pressure and temperature measurements allow designers to adapt the BME280 to a wide range of use cases.
