Barometer (BMP 280) Interface with Arduino

The BMP280 is an absolute barometric pressure sensor by BOSCH. Its small dimensions and its low power consumption allow for the implementation in battery-powered devices as mobile phones, GPS modules, or watches. We can interface this sensor with Arduino using SPI or I2C communication.

Items required:

• Arduino Nano
• BMP280
• Jumper Wire
