This page proposed an intelligent radiator which used MCU AT89S52 as the core, mainly consist of temperature and humidity detection part, main control part, display part, control part. Firstly, collect the temperature and humidity of the environment by using DHT11 temperature and humidity sensors. And then sends the data to STC89C52RC computer for analysis and processing. After the data was processing, on the one hand, the data is displayed through the LCD display LCD1602, on the other hand, the data compare to program setting of the temperature and humidity range, to control the heating device, cooling equipment, humidifying device, dehumidifying device and a buzzer. This design has reached all the expected requirements after debugging
