基于ATmega2560的多传感器红外遥控智能LED控制器

The Infrared Remote Intelligent LED Controller with Multi-sensor Design Based on ATmega 2560

设计了一种基于ATmega2560的红外遥控智能LED控制器,同时集成了人体热释电红外传感器、温湿度传感器、光照传感器和时钟芯片,具有三路PWM控制电路,在调光调色温的同时,可对具有彩光功能的LED光源进行颜色调节。集成传感器可实现单独手动开启和关闭功能:红外传感器开启后,可在适当的时间段内,实现人来灯亮,人走灯灭的效果;光传感器开启后,可采集周围环境光信号,并根据外界环境光自动调节LED光源的亮度;温湿度传感器开启后,可采集周围环境温湿度数据并显示,也可根据外界温度范围,自动调节LED光源的色温,当温湿度超过正常范围后,蜂鸣器会发声报警,对用户起到一定的提醒作用。该控制器既可通过红外遥控控制,也可通过墙面按钮控制,环保节能,适用于普通家庭场景照明,具有一定的市场价值。

This paper designs an infrared remote intelligent LED controller based on Atmega2560, which was integrated with a human body infrared sensor, a temperature and humidity sensor, a light sensor and a clock chip. It has three PWM control circuits to adjust the color temperature and brightness, as well as the color if the light permits. The integrated sensors have their own switches to control： when human body infrared sensor is enabled, the lights can be switched automatically following people＇ s activities; when the light sensor is enabled, the brightness is adjusted according to the outside lightness. When temperature and humidity sensor is enabled, the current temperature and humidity outside can be displayed on the LCD screen. The color temperature may go with the current temperature. The buzzer rings when the current temperature and humidity outside is beyond the normal range. The controller can be operated with infrared remote control as well as metope button. It is an energy conservation and environmental protection system with quite a market value.
