Description Android USB temperature and humidity sensor, HID driverless type, temperature, humidity, and barometric pressure data acquisition cable. Supports Android operating system. This product requires a phone or tablet with OTG functionality to operate. Phones without OTG functionality cannot use it. Please confirm your phone’s OTG support before purchasing. For any questions, please contact customer service. Supporting software features: Real-time display of current temperature and humidity values; real-time display of temperature and humidity curves, supporting left and right dragging to view previous temperature and humidity curves; double-click to select display only temperature curve, only humidity curve, or both temperature and humidity curves; configurable display of upper and lower temperature and humidity ranges; temperature and humidity list display. If you need to programmatically read the data, we can provide an app that supports Android broadcast message mechanism for data transmission. However, this mechanism requires our app to be installed. This app periodically reads the device’s real-time data and broadcasts it. You can then add broadcast reception to your own app to obtain the real-time data. We can provide an Android Studio project broadcast reception example. This product is a driverless HID simulation model.
