Scalable Thermohygrometer Design Based on STC8H8K64U-TSSOP20

Overview

This is a scalable temperature and humidity meter design based on the STC8H8K64U-TSSOP20 chip, with all chip pins exposed for easy further development. It provides serial port test code for the DHT11 temperature and humidity sensor, and a 4-pin OLED display interface with IIC communication protocol for engineering temperature and humidity display and debugging. The onboard WS2812B tri-color LEDs can be used to read the DHT11 temperature and humidity sensor's OLED display temperature and humidity

via serial communication , enabling RGB color lighting and breathing light effects.
