This design has designed a wearable air conditioning vest system for the temperature requirements of the working environment in various industries. The system uses STM32C8TC as the main control chip, collects data with three temperature sensors and displays the average temperature through the OLED screen. By manually setting the refrigeration and heating mode and the temperature value, it can also save the set temperature value, which is the circuit with memory function. The circuit can detect the change of three temperatures in the vest. If the heating mode is turned on, the relay drives the heating plate for heating when the temperature is lower than the set temperature. At the same time, the red LED lights are bright. When the set temperature is reached, the relay is disconnected. When the temperature is detected to be two degrees lower than the set temperature, it begins to heat, so as to keep the temperature within the set range. Similarly, the refrigeration mode is also the same. In addition, the display circuit can observe the average temperature of the current three temperature sensors, and has red green LED and buzzer tips.
