Magnetic Door Sensor Circuit Diagram

Assemble the circuit on a small pcb and enclose in a suitable box.

Magnetic door sensor circuit diagram.

A relay switch is used at the output of the circuit from which you can connect the connection of an ac lamp that you want to open. The circuit will also require a small size of permanent magnet to be fitted on the corner of the door in front of the reed switch that will be placed at the boarder of the door. We have previously interfaced hall sensor with arduino and made few projects using hall sensor. Fix the hall sensor hs1 at the corner of door frame and the magnet on the door keeping its south pole s oriented towards the marked side of hs1.

Align the hall sensor and magnet such that when the door is closed led1 lits steadily. Frequency of tone can be adjustable by using an attached rv1 potentiometer. Circuit diagram and explanation. If you want to protect some door from unwanted access then you can use this simple door open alarm circuit using reed switch.

In this magnetic door alarm circuit we have used a 555 timer ic in astable mode to generate a tone as an alarm. Collection of magnetic door lock wiring diagram. Circuit diagram construction and working here reed switch acts as a sensor to detect the door position close open. A wiring diagram is a streamlined conventional pictorial depiction of an electrical circuit.

When this device exposed to the magnetic field then ferrous materials inside.
