Design of Semiconductor Refrigeration System Based on MCU

Semiconductor refrigeration, as an emerging refrigeration technology, is a promising refrigeration method with a series of advantages such as cleanliness, no noise pollution, no harmful substance emissions, long lifespan, durability, high reliability, and good stability. It meets the requirements of green environmental protection and has important strategic significance for the sustainable development of the national economy; Therefore, this article proposes a semiconductor refrigeration system design based on a MCU. The entire system is controlled by a MCU as the core controller, which receives feedback signals from temperature sensors, processes them through internal temperature comparison algorithms, drives relays to control the cooling operation of semiconductor refrigeration chips, and displays the current temperature value and set temperature value on the LCD screen; At the same time, communicate with the Bluetooth communication module through the serial port to send the current temperature value in real-time to the Android mobile app for display.
