摘　　要：该系统以AT89S52单片机为核心控制器,利用热释电红外传感器检测人体信号,利用光敏电阻来探测教室中的光信号,利用温度传感器18B20来检测教室中的温度信号。当教室有人且温度较高时开启风扇,当教室有人且光线较暗时开启灯光,教室无人时关闭灯光和风扇,完成教室灯光和风扇的智能控制,有效的节约了能源和人工成本。AT89S52 is the core controller in the system. Body signals is detected by PIR optical signals and photo resistor. Temperature signal is detected by 18B20. The fan in the classroom is turned on when someone is there and temperature is higher. The light in the classroom is turned on when someone is there and light is weak. The lights and fans are tumed off when nobody is in the classroom. Through which lighting and fan are controlled intelligently, the energy and labor costs are effectively saved.
