Learn how to make lm358 based ir proximity sensor at home.
Ir proximity sensor touchless door bell theory.
This circuit is very useful for the shorter persons if he she can t press the doorbell switch then the circuit will automatically sense the person and.
When show our hand infront of ir sensor the sensor will send signal to arduino board.
In this article explain the working of ir sensor module.
In a proximity sensor an ir led and a photodiode is used to find a obstacles.
So i get this sensor set up on well from utube and follow each one by one.
The sensor can detect making touchless motion possible.
Mode control by setting the mode bit of configuration register 11h is31se5000 operates in motion mode or proximity mode.
Project file on the free design tool.
Automatically the sensor will sense the object or the person hence the sound will produce at the door.
And finally the bell will ring.
There are many ir modules available online which are cheap they cost about 200 or about 2 3.
All connections are i follow but the result i get is.
This is my first entry about hardware on sensor for my uni hardware assignment.
Interface the ir sensor module.

The existing doorbell can convert to a touchless doorbell.
Contents declaration certificate acknowlwedgements 1.
When the mode bit is.
The ir led transmits light in forward direction when an obstacle is ahead the light reflects and the photodiode is activated by this method obstacle is detected.
Hello all from all about circuits.
Ir proximity sensor report file.
If the house owner is using the automatic doorbell system with the object detection then the visitor need not to search for the switch of the door bell.
And arduino drive the relay.
Relay is connected with doorbell.
If the visitor comes to the house first he she searches for the doorbell.
