With the popularization of puters, technology formed a puterbased system with some external devices. But the more external devices to connect more with the line also. As the social security needs, electronic alarm prehensive technology is constantly evolving. At the same time, infrared technology has bee an important part of advanced science and technology. As infrared detection monitoring, it has the capability of wellconcealed and strong antijamming. This design is use of electric circuit control technology and infrared detection technology to achieve muchchannel wireless alarm system based on infrared sensor. In this paper, a fourchannel wireless alarm system based on infrared sensor is designed by the use of HN911 as infrared detection module and by the use of VD5026 \ VD5027 as the encoding\decoding chip. When a moving object entered the detection range, The highfrequency radio transmitter can emit AM signal. The receiver can send off the sound and light alarm. The system is mainly posed of fourchannel wireless transmitter based on infrared sensor and a receiver with sound and light alarm. The system features are low cost, small size, low power consumption and easy installation. It has some value in the multi field of security in order to meet the demand of ordinary.
