BME280 Atmospheric Sensor

Bosch has stepped up their game with their new BME280 Atmospheric Sensor, an environmental sensor with temperature, barometric pressure, and humidity! This sensor is great for all sorts of weather/environmental sensing and can even be used in both I2C and SPI!

This precision sensor from Bosch is the best low-cost sensing solution for measuring humidity with ±3% accuracy, 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!

BME280 Atmospheric Sensor Specification:

Supports I2C and SPI interface.
Barometric Pressure absolute accuracy: ±1hPa
Temperature accuracy: ±1.0°C
Power consumption: ±2.7uA
Supply Voltage: 1.71V ~ 3.6V
Using barometric pressure, altitude can be calculated within ±1m accuracy.
