Anti-pollution intelligent window control system based on air detection

Abstract This paper introduces a new type of intelligent window automatic control system. With single-chip microcomputer STC89C52 as the central control unit and wind speed sensing, raindrop sensing, temperature and humidity sensing, CO sensing, CO 2 sensing and formaldehyde sensing as the signal detection unit, it operates with the dual energy supply of solar energy and power grid to sense outdoor meteorological changes and indoor and outdoor air quality in real time, and performs data processing through single-chip microcomputer. The stepper motor is controlled to open and close the window to improve indoor air quality in an environmentally friendly way. At the same time, the other end of the window is connected to the display screen, which concretely displays the data and status of the window operation. The control system has the functions of automatically closing the window on rainy days, automatically opening the window when the indoor harmful gas exceeds the standard, and remote infrared control of the window opening/closing.
