[Tuya Smart] Thermohygrometer based on Tuya Smart

Before the establishment of this project, the WBR3 WiFi&BT dual-mode module was selected on the Tuya IoT platform, and then component selection and schematic design were carried out in the Lichuang EDA editor according to the relevant video tutorials.

• Function description:
• You can check the temperature and humidity conditions in the environment where the sensor is located through your mobile phone, allowing you to better understand your living environment.
• Hardware Configuration:
• MCU:STC8A8K64S4A12_C84390 chip
• USB to TTL downloader
• The WiFi module uses Tuya Smart's WBR3 WiFi&BT dual-mode module, which can be connected to Tuya Smart APP for easier viewing.
• The 3.3V power supply is output by AMS1117-3.3
• Using SHT30-DIS-B temperature and humidity sensor
• Buzzer is used to remind high or low temperatures
• LED lights for status display
• Add a button to the reset circuit for reset processing
