摘要:

系统以AT89C52单片机作为控制装置的智能部件,采用热释红外传感器检测人体的存在,采用光敏三极管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,避免了用电浪费。

关键词: 教室灯光控制, 热释红外传感器, 光敏电阻, AT89C52

Abstract:

This system to AT89C52 single chip computer as control device of intelligent parts,adopts heat release infrared sensor detects the release of human existence and adopts photoconductive resistance constitutes circuit testing environment light intensity.According to the classroom light conditions and  the measured the signal of human body system and ambient light,the system can make reasonable and intelligent judgment and then controls the work of classroom lighting circuit.It is a effective way to avoid the classroom of waste electricity.

Key words: auto-control system of classroom lights;heat release infrared sensor;photoconductive dynatron;AT89C52
