The BME280 Atmospheric Sensor Breakout measures barometric pressure, relative humidity, and temperature from a single compact board. With both Qwiic (I2C) and 0.1″ header connections, it integrates easily into Arduino, Raspberry Pi, and other microcontroller projects — no soldering required when using the Qwiic connector.

The BME280 sensor measures atmospheric pressure from 30 kPa to 110 kPa and draws less than 1 mA, making it well suited for battery-powered weather stations and environmental monitors.

Key Features

• Three-in-One Sensor – Barometric pressure, relative humidity, and temperature
