Design and Implementation of a Wireless Control Intelligent Humidifier

A wireless-controlled intelligent humidifier is developed based on the STC89C52 microcontroller. It can effectively monitor the current environment and automatically adjust the humidity level. The hardware mainly includes the STC89C52 control system, sensor circuit, alarm circuit, display circuit, keypad circuit and so on. The software is developed using Keil. It mainly includes main program, data acquisition subroutine, display subroutine, alarm subroutine, communication subroutine, etc. It not only achieves automatic detection and adjustment of indoor temperature and humidity, but also automatic detection of water level and turbidity with over-limit alarm. In addition, A mobile APP is developed to monitor and control the humidifier remotely.
