DESCRIPTION

The BME280 Environmental Sensor (Temperature Humidity Barometer) provides a precise measurement of not only barometric pressure and temperature, but also the humidity in the environment. The air pressure can be measured in a range from 300 hPa to 1100hPa with ±1.0 hPa accuracy, while the sensor works perfectly for temperatures between - 40℃ and 85℃ with an accuracy of ±1℃. As for the humidity, you can get a humidity value with an error less than 3%.

Owing to its high accuracy on measuring the pressure, and the pressure changes with altitude, we can calculate the altitude with ±1 meter accuracy, which makes it a precise altimeter as well.

Note: As the sensor is quite sensitive to the environmental conditions, please DO NOT touch it with your fingers.
