BME280 working principle

Hi, I'm using a Bosch BME280 sensor for measuring temperature, relative humidity and pressure.

I need to know which are the working principles of the sensor for temperature, relative humidity and pressure.

Thanks for anyone that helps.

Hi,

BME280 = BMP280 + humidity sensor. BMP280 working principle is decribed a little on page 3 of BMP280 datasheet at https://www.bosch-sensortec.com/media/boschsensortec/downloads/datasheets/bst-bmp280-ds001.pdf. Due to IP concern we cannot disclose more about BME280 humidity part working principle.

Thanks.
