BME680 Temperature And Humidity Pressure Sensor

The BME680 is a digital 4-in-1 sensor with gas, humidity, pressure and temperature measurement based on proven sensing principles. Its small dimensions and its low power consumption enable the integration in battery-powered or frequency-coupled devices, such as handsets or wearables.

Applications:

1.  Indoor air quality
2.  Home automation and control
3.  Internet of things
4.  Weather forecast
5.  GPS enhancement (e.g. time-to-first-fix improvement, dead reckoning, slope detection)
6.  Indoor navigation (change of floor detection, elevator detection)
7.  Outdoor navigation, leisure and sports applications
8.  Vertical velocity indication (rise/sink speed)
9.  etc……

Target Devices:

1.  Handsets such as mobile phones, tablet PCs, GPS devices
2.  Wearables
3.  Home weather stations
4.  Smart watches
5.  Navigation systems
6.  Gaming, e.g. flying toys
7.  IOT devices
8.  etc…..
