SparkFun Atmospheric Sensor Breakout - BME280 (Qwiic)

The SparkFun BME280 Atmospheric Sensor Breakout is an easy way to measure barometric pressure, humidity, and temperature readings, all without taking up too much space. Basically, you can find out anything you need to know about atmospheric conditions from this tiny breakout. The BME280 Breakout has been designed to be used in indoor/outdoor navigation, weather forecasting, home automation, and even personal health and wellness monitoring. Utilizing our handy Qwiic system, no soldering is required to connect it to the rest of your system. However, we still have broken out 0.1"-spaced pins in case you prefer to use a breadboard.

The on-board BME280 sensor measures atmospheric pressure from 30kPa to 110kPa as well as relative humidity and temperature. The breakout provides a 3.3V SPI interface, a 5V tolerant I2C interface (with pull-up resistors to 3.3V), can be configured to take measurements with less than 1mA of current draw.


The SparkFun Qwiic Connect System is an ecosystem of I2C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong.

The BME280 Atmospheric Sensor Breakout can also be automatically detected, scanned, configured, and logged using the OpenLog Artemis datalogger system. No programming, soldering, or setup required!

Measure temperature, humidity, barometric pressure with the SparkFun Atmospheric Sensor Breakout BME280 (Qwiic).

Core Skill: Programming

If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.

2 Programming

Skill Level: Rookie - You will need a better fundamental understand of what code is, and how it works. You will be using beginner-level software and development tools like Arduino. You will be dealing directly with code, but numerous examples and libraries are available. Sensors or shields will communicate with serial or TTL.

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

2 Electrical Prototyping

Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

  • Under Features it says "Temperature Range: 0°C-65°C (32°F-149°F)" but the BME280 Bosch datasheet says the temperature range is -45C to +85C. Is this an error? I noticed the non-Qwiic BME280 page says the temperature range is indeed the larger one. Later in the datasheet it says "full accuracy" in the narrower temperature range, but that doesn't bother me. But showing the narrower range in the features list made me worry it wouldn't work at all below zero. I think this is confusing.

    • I think I modified it to the full accuracy range because of feedback from another customer. However, you are correct, there is a wider operational range. I'll update the list with both ranges.
