[Tuya Smart] [Training Camp] Temperature and Humidity Sensor

The graffiti surface development module is used to implement the temperature and humidity sensor based on Lichuang EDA. 1. The face-to-face development plan adopted does not require coding. 2. The temperature and humidity sensor chip is difficult to solder for novices. You can consider replacing other chips in the future. Other components are basically packaged in 0603, which is convenient for manual welding. 3. The actual temperature can be obtained normally, but the temperature obtained is too high. Consider two possible reasons: 1) The temperature and humidity sensor is damaged (the most likely possibility, after all, the soldering iron has been used for a long time) 2) It should be considered an improvement point, and the top layer of the chip and The bottom layer of copper is left blank to avoid the influence of circuit heating (the actual impact is basically not significant)
