Grove - Temperature&Barometer Sensor (BME280)

Description High accuracy Absolute accuracy of ±1.0 hPa for pressure ±1 accuracy for temperature and ±3% for humidity Easy-to-use Grove Compatible Interface Supports both I2C and SPI communication Can be used as an altimeter with accuracy of ±1 meter The Grove - Temperature & Barometer Sensor (BME280) is based on new BME280 sensor, which is even superior to BMP280 used in Grove – Barometer Sensor (BMP280), and any other former versions like BMP180 used in Grove – Barometer Sensor (BMP180). The module provides precise measurement of not only barometric pressure and temperature, but also the humidity in the environment.
