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.
