BMP280 Barometric Pressure and Altitude Sensor I2C/SPI Module
BMP280 Barometric Pressure and Altitude Sensor I2C/SPI Module is a cheapest and tiny Atmospheric Sensor Breakout to measure barometric pressure, and temperature readings all without taking up too much space.
- Operating Voltage: 1.71V to 3.6V – would typically be operated from 3.3V.
- Operating Temperature: -40 to +85 deg. Celsius (full accuracy between 0 and +65 deg. C).
- Peak current: 1.12mA.
- Operating Pressure: 300 hPa to 1100 hPa.
- Accuracy between 700 to 900hPa and 25 to 40 deg. C: ±0.12hPa and ±1.0m.
