DFRobot_BME280

中文版

BME280 is an environmental sensor that integrates onboard temperature sensor, humidity sensor and barometer. The sensor has high precision, multiple functions, and a small form factor. It provides both SPI and I2C interfaces, which make it easy to make fast prototypes. It can be widely used in environmental monitoring, story height measurement, Internet of Things (IoT) control and other various enviroment related ideas! Tge Gravity I2C BME280 Environmental Sensor has based on BoSCH's newest MEMS sensor (Micro-Electro-Mechanical System). It is very stable when compared with similar sensors. The sensor is especially adept in air pressure measurement; it has an offset temperature coefficient of ±1.5 Pa/K, equiv. to ±12.6 cm at 1 °C temperature change. Therefore, the stable and multi-function form of the BME280 can be a perfect fit in many scenarios.
