Temperature controlled semiconductor water cooling system based on GD

Overview

The temperature-controlled semiconductor water-cooling system based on GD microcontroller
has two temperature sensors, one detects the room temperature and the other detects the water temperature. The power of the semiconductor refrigeration chip is adjusted through PWM to maintain a constant temperature difference between the water temperature and the room temperature.
It has an OLED display that can display room temperature and water temperature. It integrates a typec power module and can take up to 12v voltage. It supports QC, PD and other general protocols.

Actual measurement is available, the following is the running chart
