教室灯光智能控制系统设计

Design of Intelligent lighting control system of classroom

本文以热释电红外感应原理和STM32为基础设计了教室灯光智能控制系统。该系统电路由热释电人体红外传感器、继电器,STM32等工作电路组成。利用热释电红外传感器探测人体红外线变化,对室内的灯进行自动控制,当检测到教室内有人进入时(含人在时),控制系统会将灯自动开启;当人走时系统控制灯延时后关闭。完成人在灯亮,人走灯灭的效果。

This paper designs an Intelligent control system of classroom based on the principle of Pyroelectric Infrared Radial Sensor and STM32. This system is consisted of Pyroelectric Infrared Radial Sensor, relays, STM32 and other operating circuits.It can use Pyroelectric Infrared Radial Sensor to detect the changes of human body＇ s infrared, and control the indoor lamp automatically.When the system detects people entering the classroom（including people in）, lamp will light automaticaUy.Otherwise, it will make the lamp turn offafter the delay time .The system has the effect of ＂the lamp lighting when people enter and the lamp offwhen people out＂ .
