BME280 Barometric Pressure, Temperature & Humidity sensor i2c

Regular price £9.00

The Bosch BME280 is a combined barometric pressure, temperature and humidity sensor package. Using this breakout board you can connect it to i2c ports of a Raspberry Pi, Arduino, Wemos D1 mini etc. and read precision values for all three measurements. It's very convenient to have all three sensors on one device. It means less wiring and a potentially much more compact installation. A must-have if you're setting up a weather station or data logger.
