### I2C Air Temperature, Pressure and Humidity Sensor Board (BME280) ### I2C Air Temperature, Pressure and Humidity Sensor Board (BME280)
The sensor board is 13mm by 10.5mm in size that provides the air temperature, pressure and humidity values over I2C protocol. Sensor board uses **BME280** IC. The sensor board has 4 pins and is 13mm by 10.5mm in size. The sensor BME280 measures relative ambient temperature, barometric pressure and relative humidity, and passes measured values via I2C protocol.
