## Description

Bosch sensor module for measuring atmospheric pressure and temperature, ideal for Arduino projects and other development boards. It communicates quickly via I2C or SPI and operates with 5V logic, providing stable and accurate readings. It can be used as an altimeter with an accuracy of approximately 1 m, and pressure and temperature measurement can be enabled or disabled independently.
Atmospheric pressure and temperature sensor with Bosch BMP280 sensor, uses I2C and SPI, compatible with Arduino and other development boards.
The module operates at a logic voltage of 5V.
The module can also be used as an altimeter when using the pressure sensor, with an approximate accuracy of 1 meter, because when altitude changes, atmospheric pressure also changes.
Any of the 2 sensors (pressure, temperature) can be disabled independently.
The model is BMP280, the one without the humidity sensor, not to be confused with BME280.
Specifications:
Model: BMP 280
Input voltage: 5VDC
Logic voltage: 5V
Interface: I2C (up to 3.4MHz), SPI (up to 10MHz)
I2C address: 0x76
Temperature: -40C - +85C, resolution 0.01C, accuracy +-1C
Atmospheric pressure: 300 - 1100hPa, resolution 0.18Pa, accuracy +-1Pa
Test code:
The module is not directly compatible with the Adafruit library. It requires changing the I2C address from 0x77 to 0x76.
