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.
Ir proximity sensor touchless door bell theory.
When show our hand infront of ir sensor the sensor will send signal to arduino board.
The existing doorbell can convert to a touchless doorbell.
Automatically the sensor will sense the object or the person hence the sound will produce at the door.
There are many ir modules available online which are cheap they cost about 200 or about 2 3.
In a proximity sensor an ir led and a photodiode is used to find a obstacles.
And finally the bell will ring.
Hello all from all about circuits.
This is my first entry about hardware on sensor for my uni hardware assignment.
When setting the mode bit to 0 is31se5000 operates in the motion mode.
In this article explain the working of ir sensor module.
If the visitor comes to the house first he she searches for the doorbell.

So i get this sensor set up on well from utube and follow each one by one.
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.
This sensor can work as a touchless door bell.
