[Tuya Smart] Intelligent monitoring of ambient temperature and humidity

This is the first time I have used Lichuang to complete a specific project. Because I am a novice, I don’t know a lot and I have learned a lot. Designing a temperature and humidity sensor with zero code, from designing the USB serial port power supply, to using the temperature and humidity sensor, and then using Easy EDA to design the PCB according to the PCB schematic diagram provided by Tuya's BT5S Bluetooth module. Design features of this training camp work: 1. USB powered, easy to use. 2. You can use your mobile phone’s Bluetooth to connect devices to realize the Internet of Things function. 3. Reserve pin headers, through which temperature and humidity data can be obtained, which is helpful for further development. Judging from the results, the device can be connected to the network normally and the mobile phone can connect to the device, but the mobile phone cannot obtain data. There may be something wrong with the PCB schematic design. Although it is a bit regretful, through this training camp to learn the design process, I became familiar with the module selection, schematic drawing, PCB drawing, PCB proofing, component purchase, cloud platform construction and other processes, and gained a lot.
