product reviewDFRobot's BME280 sensor first caught my eye with all of its attractive functions, which includes:
1. The sensor's ability to measure four critical environmental factors (temperature, humidity, altitude and pressure) with ease, simultaneously. 2. It's wide operating temperature range (-40°C ~ 85°C), making this sensor durable when operating in the harshest of environments. 3. The sensor's small operating current of 2 mA, so that portable power supplies or small batteries can easily power up this sensor when needed. 4. The small size of this sensor, with its helpful Gravity i2c/UART connector and mounting holes. 5. The BME280's dual communication interface (i2c or SPI interfaces) for easier hardware/data connections to a micro controller or programmer. pinout
