It can be connected to a microcontroller with I2C (integrated with Grove socket) or through an SPI bus. We have also provided a highly abstract library to make this product easier to use. The BME280 is an upgraded version of BMP180, and BME280 gets dramatic improvements from BMP180. BME280 comes with a smaller footprint, lower power consumption, lower noise measurements, higher resolutions for pressure and temperature, lower RMS noise, a newly added SPI bus, more measuring modes, a higher measuring rate, and a newly added filter against environmental interference. Since the atmosphere pressure reading is affected by altitude and temperature, we have added compensation features. Hence, Grove - Temp&Humi; Barometer Sensor (BME280) will be more reliable in providing precise temperature, atmospheric pressure values, humidity, and approximate altitude data.
