Pressure Temperature Humidity BME280 (I2C)

File:TArduinoBME280I2C.png

Summary

The Pressure Temperature Humidity BME280 component reads atmospheric pressure, temperature, and humidity data from a Bosch BME280 sensor. It communicates using the I2C interface and outputs the measured values.

Description

The BME280 is an integrated environmental sensor that combines high-precision measurements of pressure, temperature, and humidity in a single device. It provides calibrated digital output and communicates through the I2C interface. The sensor offers configurable averaging and filtering options for all three environmental parameters. Typical applications include comprehensive weather stations, indoor climate monitoring, and advanced environmental data logging systems.
