In this article explain the working of ir sensor module.
Ir proximity sensor touchless door bell theory.
And arduino drive the relay.
Infrared light sensor with advanced signal processing and digital output.
There are many ir modules available online which are cheap they cost about 200 or about 2 3.
Interface the ir sensor module.
This sensor can work as a touchless door bell.
This is my first entry about hardware on sensor for my uni hardware assignment.
Project file on the free design tool.

If the visitor comes to the house first he she searches for the doorbell.
Hello all from all about circuits.
Ir proximity sensor report file.
Contents declaration certificate acknowlwedgements 1.
So i get this sensor set up on well from utube and follow each one by one.
The existing doorbell can convert to a touchless doorbell.
And finally the bell will ring.
Relay is connected with doorbell.
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.
All connections are i follow but the result i get is.
Automatically the sensor will sense the object or the person hence the sound will produce at the door.
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.
In a proximity sensor an ir led and a photodiode is used to find a obstacles.
When show our hand infront of ir sensor the sensor will send signal to arduino board.
The sensor can detect making touchless motion possible.
When setting the mode bit to 0 is31se5000 operates in the motion mode.
When the mode bit is.
