Take advantage of the opportunity provided by Lichuang to try to make a simple functional board yourself. The temperature and humidity display is based on HK32F030MF4P6. The screen uses an OLED screen with IIC interface, the temperature and humidity sensor uses SHT31, and USB micro provides power supply and communication.
The measured temperature and humidity conditions are displayed in real time on the OLED screen, and can also be transcribed via USB cable communication, supporting the modbus rtu protocol.
