Pressure Temperature BMP280 (I2C)

File:TArduinoBMP280I2C.png

Summary

The Pressure Temperature BMP280 component reads atmospheric pressure and temperature data from a Bosch BMP280 sensor. It communicates using the I2C interface and outputs the measured values.

Description

The BMP280 is a high-precision digital pressure and temperature sensor designed for atmospheric pressure measurement. It provides calibrated digital output and communicates through the I2C interface. The sensor offers configurable averaging and filtering options for both pressure and temperature readings. Typical applications include weather stations, altitude tracking, and environmental monitoring systems.
