The BMP280 is a high precision pressure sensor module from Bosch. The sensor can measure both atmospheric pressure and temperature with an accuracy of 0.1hPa and 0.1*C respectively. It is commonly used in barometer or altimeter. It operates on 3.3V and can communicate through both SPI and IIC.

• Operating voltage: 1.7V to 3.6V
• Maximum Current: 1.12mA
• Temperature range: -40 to +85 deg.C
• Pressure range: 300hPa to 1100hPa
• Output: SPI and IIC protocol
