摘 要日常生活中电能浪费现象比较严重，就以室内照明为例，由于使用人员不固定以及人员的节能意识的淡薄，白天室内照度很高的情况下，仍然普遍存在开灯作业；即使室内无人或者人数很少的情况下，也是全部开启室内照明。长明灯比比皆是，人走不熄灯的现象到处存在。本文通过热释型红外传感技术，利用人体的温度作为检测目标。当人进入其探测区域内，红外传感器将人体与空间温度的差值传递给信号处理系统，从而实施对控制电路的驱动与否，实现对控制对象的具体控制，最终由单片机对房间内人数和光线的综合实时控制。根据实际情况自动控制灯的开关，这样就会杜绝严重的浪费现象，并且具有明显的经济价值。关键字：单片机，热释红外传感器，光传感器，照明控制，节能Abstract The waste of electricity in daily life is serious, take the interior lighting as an example, because the use of personnel is not fixed, and the weak staff awareness of energy saving, during the day under the high intensity of light, people still keeping lights on work; although small number of cases, they turn on all of the lights; Besides, people do not turn off the lights when they leave.In this paper, pyroelectric infrared sensing technology is used, it takes the body's temperature as the test target. When people entering the detection region, the infrared sensor tests the temperature difference between the body and the space, and passes the signal to the processing system, to implement control circuit or not to realize the control object of the specific control, the end of the room by the microcontroller , and the number of real-time control of light. Automatic control based on the actual situation of light, this will eliminate a serious waste and has significant economic value.Keywords：single chip computer，pyroelectric infrared sensor， light sensors，illumination control，energy saving目 录摘 要..................................................................iAbstract....
