Abstract: This article mainly introduced the STC89C52 microcontroller based intelligent window control system design. System means to design a set of rain, indoor temperature measurement and display, and can realize manual control and automatic control of switching three functions in one of the based on single chip microcomputer intelligent window. In order to achieve intelligent product demand, intelligent window control system USES a variety of sensor technology, with the rain sensor and temperature sensor as the main body. System USES STC89C52 single-chip microcomputer for micro controller. STC89C52 is responsible for the collection and indoor temperature, automatic rainproof and manual adjustment function. Through the measurement and control system of temperature sensor, interval of measuring indoor temperature, and temperature, and the date/time by the LCD display. When rainy days, single-chip microcomputer control system by the rain sensor signals, automatic action to close the window. To humanized design, this system also has the manual control button, can control the window switch by manual button. This multifunctional window design in line with safe, convenient, energy saving, humanized principle, can make modern life improved significantly.
