Advanced Weather Sensor (BME280)




Product Description

Measuring humidity, temperature and atmospheric pressure.

The humidity sensor provides an extremely fast response time for fast context awareness application and high overall accuracy over a wide temperature range.

The pressure sensor is an absolute barometric pressure sensor with extremely high accuracy and resolution.

The integrated temperature sensor has been optimized for lowest noise and highest resolution. Its output is used for temperature compensation of the pressure and humidity sensors and can also be used for estimation of the ambient temperature.
