Specification

Description

This Gate open alarm kit can be attached to any door. If the door opens, it will generate an alarm. The main component used here is the Reed switch or magnetic switch. If any magnet comes near the reed switch, it becomes closed otherwise it remains open. Hence a magnet can be attached to the door, if the door is opened, the magnet will go away from the sensor and it will be activated.

The Gate open alarm switching of buzzer and led is done here through a transistor. As long as the magnet is there near to the reed switch, the base of the transistor Q1 remains connected with the ground and hence transistor Q1 remains off. If the reed switch becomes open, the base of the transistor (V3) goes at high voltage, and hence the transistor gets turned hence the buzzer and led become on.
