Hello dear friends;
In this project , i have tried to explain how to use PIR Motion Sensor(HC-SR501) with an Arduino...
As most of you know, it is using in the WC's, buildings and homes in order to lower electricty bills.
In fact , you can make your own HOME AUTOMATION if yo want to lower your bills :) Only thing you have to do is using relay with this sensor...
For how to use relay module with an Arduino pls read this article and watch the video:Click here
But how this sensor works? It is very simple....Basically this sensor scanning the area and differentiate the radiation difference.If there is a difference it means there is a movement .(Every obstacle , human or animal got some radiation ). If movement occur, PIR Sensor send 1 LOGIC Signal into Arduino, contrast; PIR Sensor send 0 LOGIC Signal into Arduino.So we can use this system with Arduino and we will be able make some automations....

All the codes(arduino) and circuit diagram (fritzing) has been uploaded here and on github(some kind of Turkish letters if you use github link):Codes and circuit(fritzing) from github CLICK HERE
If you guys like my projects and if they help, please LIKE my videos so that i understand they are helpful and keep going for new projects :)
If any question or suggestion, here or on YouTube channel please...
Good Luck,Have Fun!
Sorry for my English if i made mistakes :/
