In this project, Multi Gate Door Bell can be used as a security system. We can do this in a house, office for the security region. If someone forcibly opens the gate an alarm will sound. In this, we have used some simple components like a transistor, magnetic switch, buzzer, and sum resistor & capacitors.
The Multi Gate Door Bell Sensor purpose for making this project is that we can do it for security purposes. We can fit this kit in 3 different doors. You simply need to fit a small unit including a reed switch on each door frame and fix a magnet on the moving door such that the magnet aligns with the reed switch when the door is closed. As long as the door is closed, no sound will be generated, as soon as someone opens the door, and then in that condition, the contact of the reed switch will be removed from the magnet and the buzzer will ring. You have to do the same process in all three doors.
