Design of temperature and humidity control system based on Single Chip Microcomputer

This paper presents a temperature and humidity control system based on STC89C52, which mainly includes hardware design and software design. Hardware design part completes the electronic components selection, circuit design and debugging, software design part completes the preparation of each function module subprogram and system main program. The system designed in this paper can drive the working state of the back-end equipment in real time according to the temperature and humidity value in the current working environment, so as to effectively control the effect of indoor temperature as well as humidity, so as to reduce the occurrence of aging weapon equipment and abnormal work accidents caused by the temperature and humidity exceeding the predetermined value.
