BMP280 Sensor Module

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.

New BMP280 sensor, an environmental sensor with temperature, barometric pressure that is the next generation upgrade to the BMP085/BMP180/BMP183. This sensor is great for all sorts of weather sensing and can even be used in both I2C and SPI!

Precision sensing solution for measuring barometric pressure with ±1 hPa absolute accuracy, and temperature with ±1.0°C accuracy. Because pressure changes with altitude, and the pressure measurements are so good, you can also use it as an altimeter with ±1 meter accuracy.
