The BME280 is a small and low-power environmental sensor that can measure temperature, humidity, and pressure. It is ideal for mobile applications that need to save space and battery life.

Applications:

1. Context awareness, e.g. skin detection, room change detection
2. Fitness monitoring/well-being
3. Warning regarding dryness or high temperatures
4. Measurement of volume and airflow
5. Home automation control
6. Control heating, ventilation, air conditioning (HVAC)
7. Internet of things
8. GPS enhancement (e.g. time-to-first-fix improvement, dead reckoning, slope detection)
9. Indoor navigation (change of floor detection, elevator detection)
10. Outdoor navigation, leisure, and sports applications
11. Weather forecast
12. Vertical velocity indication (rise/sink speed)
    
    Features:
    1. The BME280 is a great new chip that was originally designed for the next generation of smartphones.
    2. With an I2C connection, you have access to enough weather data to make some pretty good predictions for your local area.
    3. BME280, the precision sensor, is soldered onto PCB.
    4. Not only the pressure and the temperature, but this sensor can also measure humidity.
    5. It uses both I2C and SPI (supports 3-, 4-wire SPI) interface

       Package Includes:

       1 x GY-BME280-5V Temperature and Humidity Sensor
