The BME280 is an environmental sensor that integrates a temperature sensor, humidity sensor, and barometer. It is highly accurate, with many functions and a small size. It provides SPI and I2C interfaces, facilitating the creation of quick prototypes. It can be widely used for environmental monitoring, measuring altitude, and controlling the Internet of Things (IoT).
The BME280 I2C sensor is based on the latest MEMS sensor from BoSCH. It is very stable compared to other types of sensors, especially in measuring atmospheric pressure. Its temperature shift is ±1.5 Pa/K, equivalent to ±12.6 cm for a temperature change of 1 °C, making it an excellent choice in many cases.
