Bosch BME280 Humidity & Pressure Sensor
Bosch BME280 Humidity and Pressure Sensor is an integrated environmental sensor developed specifically for mobile applications where size and low power consumption are key requirements. The unit combines individual high linearity, high accuracy sensors for pressure, humidity, and temperature in an 8-pin metal-lid LGA package. Bosch BME280 Humidity and Pressure Sensor is designed for low current consumption (3.6μA at 1Hz), long-term stability, and high EMC robustness.
The humidity sensor features a fast response time that supports performance requirements for applications such as context awareness, and high accuracy over a wide temperature range. The humidity/pressure sensor is an absolute barometric pressure sensor that features high accuracy and resolution at low noise. It is primarily used for temperature compensation of the pressure and humidity sensors, and can also be used for estimating ambient temperature. The Bosch BME280 supports a full suite of operating modes, which allows optimization for power consumption, resolution, and filter performance.
