BMP280 Barometric Pressure and Altitude Sensor

This sensor has high accuracy and low cost making it an ideal solution for precision pressure measurements of up to ± 1 hPa and a temperature of up to ± 1.0 ° C. Because the pressure changes with altitude and pressure measurements are very accurate, you can use this sensor and the altimeter ± 1 meter accuracy.
