Homemade Infrared Motion Sensor Alarm System (Using Single Infrared Beam Sensor)

Hi, guys thanks for watching my video,
In this video I made a Motion Sensor Alarm using Single Infrared Beam Sensor. I Hope you enjoy watching this video as I enjoy building it...

Wiring Diagram:https://drive.google.com/file/d/11pEyqRtUYXHQklkONexzPf_WMbxGaYhF/view?usp=sharing

The component used in this project is:
- 12V DC Power Supply
- Electrical Wire
- Single Infrared Beam Sensor
- Flasher Relay
- 4 Pin Relay
- Switch
- Siren Speaker
- Light
- Single Infrared Beam Sensor

Notes: WHY RELAY?
-If you talking about the 3-pin Relay, yes i know it's unnecessary, I just use it to make the light blinking if the alarm is triggered (Why?.. because the light that I used is just a normal light, its not blinking automatically when triggered like alarm light should be).

-If you are talking about the 4-pin Relay, this Relay is necessary to make sure the alarm keep going on once the sensor detect something pass through the sensor. Without the relay, the alarm will only be turned on when someone is standing in between the sensor, and it will be turned off immediately once the person go away from the sensor. this type of alarm has disadvantage, just imagine someone run pass through the sensor, the alarm will sound only for a split second. You might or might not realize someone just pass through the sensor. So, to solve the problem, that's why i used the 4-pin Relay, to make the alarm keep on going once the sensor are triggered and it still going on even when the person move away from the sensor. Then, if you want to reset it, just use the switch, turn it OFF and ON again to stop the alarm sound.

-Just in case if you are wondering why this is complicated, Well it's because this is not a ready made alarm system which is a "plug and play" type that everyone can get from the store. What i did here is just turning a simple basic infrared sensor into a working alarm system.
