SparkFun Atmospheric Sensor Breakout - BME280 (Qwiic)

The SparkFun BME280 Atmospheric Sensor Breakout is a compact and comprehensive solution for measuring barometric pressure, humidity, and temperature readings. This tiny breakout is capable of providing a wealth of information about atmospheric conditions, making it ideal for a range of applications including indoor/outdoor navigation, weather forecasting, home automation, and personal health and wellness monitoring. Thanks to the Qwiic system, no soldering is required to connect it to your system. However, for those who prefer traditional methods, 2.54mm-spaced pins are also available for use with a breadboard.

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

The SparkFun Qwiic Connect System is a seamless ecosystem of I²C sensors, actuators, shields and cables designed to make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector, reducing the amount of required PCB space. Plus, with polarized connections, there's no risk of incorrect hook-up.

The BME280 Atmospheric Sensor Breakout can also be automatically detected, scanned, configured, and logged using the OpenLog Artemis datalogger system. This means no programming, soldering, or setup is required, making it a user-friendly choice for beginners and experienced users alike.
