基于STC单片机的电子温湿度控制系统设计.doc

The abstract of the undergraduate thesis "Design and Implementation of Temperature and Humidity Controller Based on STC Microcontroller" is as follows: The electrical equipment in the power cabinet requires a dry and cool environment. Some electrical equipment has high resistance, and some electromagnetic coils generate a lot of heat after long working hours. The humid environment easily corrodes the electrical equipment, greatly reducing its service life. Therefore, a device that can control the temperature and humidity inside the power cabinet is needed to keep the temperature and humidity within a suitable range for the electrical equipment to work. However, manually monitoring the temperature and humidity inside the power cabinet has large errors, high randomness, and cannot provide continuous and safe monitoring. By using the STC microcontroller to monitor the temperature and humidity and control the on/off of the relay, dehumidifier, and radiator, the purpose of cooling and dehumidifying the power cabinet can be achieved. Using the microcontroller system for temperature and humidity monitoring and control inside the power cabinet can provide real-time monitoring and control with relatively small errors. It is also intuitive and easy to understand, and the temperature and humidity monitoring and control range can be adjusted through settings. This reduces the maintenance cost of electrical equipment and ensures personal safety. Keywords: microcontroller STC89C52, DHT11 sensor, temperature and humidity monitoring and control.
