ICStation team introduce you this Anti-theft Entrance Guard Alarm System based on ICStation MEGA. This system works under 5V DC power supply, it can realize infrared entrance guard monitoring and uses the active buzzer to finish alarm. This system is very Convenient and practical and can be made very easily.

Functions:
1). When turn on the power supply, the DIP LED lights, the system works normally. 2).When some object enters the infrared area, the buzzer alarms, the DIP LED stops lighting. 3).
