PRODUCT DESCRIPTION / SPECIFICATIONS
Nowadays Security is important in our whole life. Using this circuit we can solve some security issue. This circuit is IR based security alarm circuit, it detects any movement then trigger the alarm.This circuit is based on IR sensor where an IR beam is continuously falling on a photodiode, and whenever this Infrared beam breaks, by any kind of movement, the alarm is triggered.In this IR based security alarm circuit, we have placed IR LED in front of a photodiode, so that IR light can directly fall on the photodiode. Whenever someone moves through this beam, IR rays stops falling on photodiode and Buzzer start beeping. This circuit is very simple and very easy to assemble it.
Working/About the Circuit:
In this circuit, there is two parts transmitter and receiver.In transmitter side, One IC 555 is connected with the IR Led.This Led continually transmitting the signal. In receiver side, there is one IRX receiver module so it receives the signal from the Transmitting side the output of this module produces the pulses and transfer to the transistor T1.Here IC2 555 is connected so it handles the signal in time-based.If any movement occurs in between then the IC2 time is expired and send the signal to the IC3 UM66 and buzzer will be On.

Note: This Kit is Unassemble user can assemble it by on your Self.
