Barometric Pressure Sensor w Temperature Compensation_BMP180 belt This is the famous bi-polarProduct Description This pressure sensor module is used for measuring barometric pressure (weather) and altitude. It also have temperature sensor for temperature compensation of pressure measurements. It uses push sensor the BMP180. It offers a pressure measuring range of 300 to 1100 hPa with relative pressure error to 0. 12 hPa (1m height). Note: (1 hPa 100 Pa) which is equal to 0. 001 bar (atmospheric) BMP 180 is a barometric pressure sensor with an
