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
- Qwiic Connector – Plug-and-play I2C connection, no soldering needed
- 0.1″ Header Breakout – Also supports breadboard and SPI wiring
- 5V Tolerant I2C – Pull-up resistors to 3.3V included on-board
- Low Power – Less than 1 mA current draw
Specifications
- Sensor – Bosch BME280
- Pressure Range – 30–110 kPa

Jargon buster
Plain-language definitions for the technical terms used above.
- breakout
- A breakout board carries a small or fine-pitched component and brings its connections out to standard, breadboard- and header-friendly pins. Describing a part as a breakout means it can be wired into a project without soldering directly to the component's tiny contacts.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
- microcontroller
- A microcontroller is a small computer on a single chip that runs a stored program and controls connected inputs and outputs such as buttons, sensors, displays and communication interfaces. In a device built around one, it is the part that executes the code and coordinates the device's behaviour.
- Qwiic
- Qwiic is a plug-in connector system for I2C devices that uses small 4-pin cables, so you can connect compatible sensors without soldering. It matters because your controller or adapter also needs Qwiic, or you will need a cable or breakout to wire it up.
- SPI
- A fast serial communication bus often used for displays, memory cards, and sensors. It matters because SPI devices need specific pins for clock and data, plus a separate chip-select line for each device.
