BME280 Breakout - Temperature, Pressure, Humidity Sensor
A really nice environmental sensor that's ideal for indoor monitoring of temperature, pressure, and humidity, or even outdoors in a suitable enclosure. It's both Raspberry Pi and Arduino-compatible.
They use this sensor on their Enviro+ environmental monitoring board, but it's such a nice sensor that they thought to pop it onto a breakout! The BME280 is a great sensor for monitoring conditions around your home.
They've designed this breakout board so that you can solder on the piece of right-angle female header and pop it straight onto the bottom left 5 pins on your Raspberry Pi's GPIO header (pins 1, 3, 5, 6, 9). The right-angle header also has the advantage of positioning the breakout away from the Pi's CPU so as to minimise radiated heat.
- In testing, results show that the sensor requires some burn-in time (at least 20 minutes) and that readings may take a couple of minutes to stabilise after beginning measurements
- The solder pads (marked ADDR) can be bridged to change the I2C address from the default of 0x76 to 0x77, meaning that you can use up to two sensors on the same Raspberry Pi or Arduino
- The BME280, BME680, and BMP280 breakouts all share the same I2C addresses, so if you're using two together then you'll need to change the I2C address on one of them using the solder bridge/pads
