Magnetic Door Sensor Circuit Diagram

It shows the components of the circuit as simplified shapes and also the power as well as signal connections in between the gadgets.

Magnetic door sensor circuit diagram.

The reed switch is a small device and contains two ferrous materials inside. When this device exposed to the magnetic field then ferrous materials inside. We have previously interfaced hall sensor with arduino and made few projects using hall sensor. Circuit diagram and explanation.

Here we have connected a 1k. Frequency of tone can be adjustable by using an attached rv1 potentiometer. In this magnetic door alarm circuit we have used a 555 timer ic in astable mode to generate a tone as an alarm. 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.

Circuit diagram construction and working here reed switch acts as a sensor to detect the door position close open. Assemble the circuit on a small pcb and enclose in a suitable box. Align the hall sensor and magnet such that when the door is closed led1 lits steadily. Collection of magnetic door lock wiring diagram.

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.
