Abstract
This design is an intelligent humidifier system based on single chip microcomputer. The design core combines STC89C52 with the temperature and humidity sensor DHT22. The temperature signal and humidity signal are collected by the sensor, and the digital signal is converted into real-time display on the LCD with the precision of one decimal point.The single-chip microcomputer is used to analyze and process the data to realize intelligent opening and dehumidification function, and users can input preset values in advance according to their needs.When the actual measured humidity value is lower than the preset humidity standard, the humidifier automatically humidifies;When the measured humidity is higher than the preset humidity standard, stop humidifying;When the detected water level is lower than the preset 3cm, the humidifier alarms and stops humidifying.
