基于STC单片机的温湿度控制系统设计与实现.

电力设备 themselves have large resistance, some electromagnetic coils also produce a lot of heat after long-time work. The humid environment is prone to corrode the electrical equipment lines, greatly reducing their service life. Therefore, a device that can control the temperature and humidity inside the electric cabinet is needed to keep the environment within an appropriate range for the electrical equipment to work. Manual monitoring of temperature and humidity inside the electric cabinet results in large errors, randomness, and inability to continuously monitor, which is also unsafe. Using a 51 microcontroller to monitor temperature and humidity and control the on-off of relays, as well as the operation of dehumidifiers and radiators, can achieve the purpose of lowering the temperature and dehumidifying inside the electric cabinet. Using the microcontroller system for temperature and humidity monitoring and control inside the electric cabinet allows for real-time monitoring and control, with relatively small errors and intuitive understanding. The monitoring and control range of temperature and humidity can also be adjusted through settings. This reduces the maintenance cost of electrical equipment and ensures personal safety.
