[ZC] Temperature and humidity sensor based on Tuya Smart +924152A

The project uses Tuya XR3WIFI networking module for external communication; it is powered by USB or battery. The anti-tamper switch module in the Tuya Smart reference schematic diagram has been deleted; the IoT temperature and humidity sensor uses an integrated temperature and humidity probe as the temperature measurement element to collect the temperature and humidity signals and undergo voltage stabilization filtering, operational amplification, and nonlinear correction. , V/I conversion, constant current and reverse protection and other circuit processing, it is converted into a current signal or voltage signal output that is linearly related to temperature and humidity. Works are highly customizable and can be adapted to market needs. For example, if you only need to use a mobile phone APP to check the ambient temperature and humidity in real time, the device can use Tuya Smart's development-free solution, and the hardware product firmware development can be completed through online visual configuration, which is simple and easy to do.
