The Smart Door Lock Alarm System with LED is a convenient solution to control the lamp by sensing the magnet of the switch sensor alarm. The type of magnetic switch sensor alarm is normally closed. When the magnet together, the circuit is not conductive light OFF but when the magnet separates, the circuit is conductive light ON. This is an easy kit to detect the door condition which is open or close. Use a normally closed USB for USB output. When the magnetic switch sensor alarm separates, the LED lamp automatically turns on and the buzzer sounds. Meanwhile if the magnetic switch sensor alarm together, the LED lamp turns off automatically.
