BMP280 Pressure Sensor

 

This sensor can measure barometric pressure and temperature with very good accuracy. Since pressure varies with altitude, we can also use it as an altimeter with an accuracy of ± 1 meter. Barometric pressure accuracy is ±1 hPa and ±1.0°C for temperature. It is an ideal pressure sensor that you can use in Arduino projects and Raspberry Pi projects.
