中文摘要 单片机渗透到我们生活的各个领域，几乎很难找到哪个领域没有单片机的踪迹 主要是以红外热释电处理芯片BISS0001和单片机组成的红外传感控制电路。其原理是：以人体红外辐射（波长为9.5um）为传感信号，当人体在台灯的范围内且环境光强较弱时，自动感应开灯，省去黑夜摸灯的麻烦；当人离开台灯传感器检测范围，自动感应关灯。采用LM393电压比较器构成的电路检测环境光的强度；根据教室合理开灯的条件，系统通过对人体的存在信号和环境光信号的识别和智能判断，完成对教室照明回路的智能控制，避免了教室用电的大量浪费。采用模块化结构设计、条理清晰、通用性好，便于改进和扩充。该系统具有体积小，控制方便,可靠性高，专用性强，性价比合理等优点。 关键词：人体感应，教室灯，单片机，智能化 ABSTRACT Microcontroller penetrated?into every aspect of our lives,?which is almost difficult to find?traces of?the field without?MCU,?the light?is necessary for thousands of households living?supplies,?when night comes,?people?in the dark?to?light,?very inconvenient,?but when he dies,?people?often?forget to turn off the lights?and causing huge?waste of energy.
