BMP085 Barometric Sensor (300 to 1100hPa)


The BMP085 a high-accuracy barometric sensor chip which detects barometric pressure and temperature. It can widely measure pressure ranging from 300hPa to 1100hPa, AKA +9000m to -500m above sea level, with a super high accuracy of 0.03hPa(0.25m) in ultra-high resolution mode. This barometric sensor is compatible with both 3.3V and 5V logic.
