The BME680 is a low-power gas, pressure, temperature and humidity sensor. The BME680 is a digital 4-in-1 sensor that measures gas, humidity, pressure and temperature based on proven sensing principles. This sensor module is encapsulated in an extremely compact metal cover LGA package, occupying an area of only 3.0x3.0 square millimeters and having a maximum height of 1.00 millimeters (0.930.07 millimeters). Its small size and low power consumption enable it to be integrated into battery-powered or frequency-coupled devices, such as mobile phones or wearable devices. Typical applications: Indoor air automation and control Internet of Things Weather forecast GPS enhancement (for example, improvement of the first positioning time, estimated ranging, slope detection); Indoor navigation (floor change detection, elevator detection) Vertical speed indication (ascending/descending speed) for outdoor navigation, leisure and sports applications.
