Pressure Temperature BMP280 (SPI)
Summary
The Pressure Temperature BMP280 component reads atmospheric pressure and temperature data from a Bosch BMP280 sensor. It communicates using the SPI 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 SPI interface. The sensor offers configurable averaging, filtering options, and SPI communication settings for both pressure and temperature readings. Typical applications include weather stations, altitude tracking, and environmental monitoring systems requiring SPI communication.

Properties
- Averaging:
- Pressure – Number of samples to average for pressure readings (Default: 1).
- Temperature – Number of samples to average for temperature readings (Default: 1).
- Enabled – Enables or disables the component's functionality (Default: True).
- IIRFilter Coefficient – IIR filter coefficient value (Default: 0).
- In Fahrenheit – When enabled, temperature is output in Fahrenheit; otherwise in Celsius (Default: False).
- Inactive Duration – Duration of inactivity before sleep mode in seconds (Default: 0.5).
- Name – The user-defined name for the component (Default: PressureTemperature).
- SPI3Wire – Enables 3-wire SPI mode when True (Default: False).
- SPISpeed – Configures the SPI communication speed in Hz (Default: 500000).
Pins
