BME280 Barometric Pressure, humidity and Temperature sensor

The Bosch BME280 chip incorporates three sensors: a Barometric pressure sensor, a humidity sensor and an other one for temperature. this cheap but accurate sensor is perfect for all weather and environmental applications thanks to the ± 1hPa / ± 1 ° C / 3%(humidity) accuracy. With the barometer, this sensor can also be used as an altimeter with an accuracy of ± 1 meter. This sensor is also very versatile thanks to its I2C and SPI communication bus
