Design of Automatic Door and Window Closing System

This design consists of six parts: power supply, microcontroller circuit, wind detection circuit, water droplet detection circuit, lighting detection circuit, and stepper drive circuit. The first scenario is to open the doors and windows during the day, without rain or wind, and rotate them by a stepper motor for one turn; The second scenario is to close the doors and windows at night or in rainy or windy conditions, indicated by a stepper motor closing for one week; The third scenario: real-time monitoring and control of the stepper motor in case of darkness and brightness, as well as rain; The fourth situation: the triggering of wind triggers the closing of doors and windows once, and can only be reopened after closing, because the changes in wind are uncontrollable. By utilizing the above principles, the effect of automatically opening and closing the doors and windows of the warehouse according to different weather conditions can be achieved.
