Your cart is empty.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!

SparkFun's Qwicc circuits might be a little more expensive, but they are well designed and work reliably.The BME280 circuit includes options for both SPI (breakout only) and I2C (Qwiic or breakout). You can adjust the addressing, I2C pullups, power led, and chip select pullup with severable solder jumpers. It is accurate and works well with EspHome.

I am using it with an I2C lcd and it works good. I am running this with a nano compatible and the SparkFun nano shield and both products are good, support documents are nice and easy to follow. I lower the interval on the example for basic readings from 500 to 2000 (delay). You must follow SparkFun documentation, download their library and you just need to include your OLED or LCD. I prefer LCD for texts because they last for years, OLED you need to include a screensaver or something to avoid screen burnout.

In the code you have to change wire with wire1. This assumes your using qwiic. I'm using arduino r4 wifi
