The temperature and humidity sensor I chose was sht30, which was quite difficult to solder and resulted in the scrapping of three boards. The main control chip is Tuya. The voltage stabilizing chip selected is 6211C33. This is the first time I tried to use Tuya Smart’s development-free solution, temperature and humidity sensor. First, the hardware chip is customized on Tuya's official website, and then the schematic diagram is drawn, the PCB is drawn online on Lichuang EDA, and then the components are purchased through Lichuang Mall and soldered by oneself. Real-time uploading of temperature and humidity is achieved. We will continue to study MCU development solutions and try other Tuya chips in the future.
