BME280 Environmental Sensor
BME280 Environmental Sensor
User Manual
OVERVIEW
The BME280 is as combined digital humidity, pressure and temperature sensor. Its
small dimensions, low power consumption, high precision and stability allow the
implementation in environmental monitor, whether forecast, altitude detection and
IOT application.
