Gravity I2C BME280 Environmental Sensor has based on BoSCH newest MEMS sensor (Micro-Electro-Mechanical System). It is very stable to compare with other kind of sensors, especially the air pressure measurement, the offset temperature coefficient is ±1.5 Pa/K, equiv. to ±12.6 cm at 1 °C temperature change. Therefore, the stable and multi-function make BME280 become a good choice in many scenes.
