[Tuya Smart] Tuya Zigbee temperature and humidity sensor-471069R

Overview

Develop a temperature and humidity sensor based on Tuya smart module ZigBee without programming.

The sensor is SHT30

Thanks to Tuya Smart and Jialichuang for providing the training camp.

This is my first time to actually use Lichuang EDA for circuit design. After I get familiar with it, it is very convenient to use, especially the rich libraries and 3D models.

The design process refers to the schematic diagram provided by Tuya, and adds the lithium battery charging function of the USB interface. The power supply of the Tuya module is 3.3V, and the 3.7V battery voltage needs to be converted.

The APP uses Tuya’s public version APP.

The actual test was powered by batteries. From February 16th to February 27th, the battery power only dropped from 100% to 93%.

This is a larger version 70x70

This is a 50x50 version
