BMP280 3.3V Temperature and pressure sensor I2C or SPI module for Arduino

BMP280 3.3V pressure and temperature sensor

The Bosch BMP280 sensor, a direct successor to the popular BMP180, is a precise and reliable device for measuring atmospheric pressure and temperature. The module is fully compatible with popular microcontroller platforms such as Arduino, ESP8266, ESP32, and Raspberry Pi, which greatly simplifies integration in a wide range of electronic projects.

The sensor communicates via the universal I2C or SPI interface. It features a wide pressure measurement range from 300 to 1100 hPa with high accuracy of up to 1 hPa. The module is powered at 3.3V, and the built-in thermometer allows measurement from -40°C to +85°C. Everything is housed on an extremely compact board measuring just 15 x 10 mm.
