Nice Bidirectional Visitor Counter Using Arduino Circuit Diagram

Data pin of lcd d4 d7 is also directly connected to arduino at d11 d8 respectively.

Bidirectional visitor counter using arduino circuit diagram. The project of digital visitor counter is based on the interfacing of some components such as sensors motors etc. Visitor counter circuit diagram. When somebody enters the room then the counter is incremented by one.

This ir sensor is consist of two led. The outputs of ir sensor modules are directly connected to arduino digital pin number 14 a0 and 19 a5. Here we make bidirectional visitor counter using arduino and ir sensor.

We can also make it. People or visitor counters are pretty famous embedded application that was widely used in places like theaters malls transport stations and so. It is a very interesting project for hobbyists and students for fun as well as learning.

Ir sensor infrared sensor you can see the basic hardware structure of the ir sensor below. This counter can count people in both directions. And relay driver transistor at digital pin 2.

Bidirectional visitor counter a digital visitor counter is a reliable circuit that takes over the task of counting the number of persons visitors in the room very accurately. Using this circuit we can count the number of people coming or going into a room. Today we are here with a project with bidirectional visitor counter by using arduino uno.

And it can also be displayed on any screen. Today we are about to see building of simple visitor counter project using arduino which uses ir as a tool for sensing. High end counters uses sophisticated hardware to do the process of counting.
