Hello friends, i hope you all are fine and enjoying. Today i am going to share a new project tutorial which is Interfacing PIR sensor with Arduino. First of all lets, have a little introduction about the basics and working of the PIR sensor. PIR sensors are in fact a Passive Infrared Sensor. PIR sensors are actually electronic sensors and they are used for motion detection. They are also used to detect the Infrared waves emitting from a particular object. You should also have a look at PIR Sensor Library for Proteus , using this library now you can easily simulate your PIR Sensor in Proteus software. PIR sensors are widely used in motion detection projects now a days. Since my today's tutorial is about interfacing of PIR sensor with Arduino micro controller. Before going to that it is nece ...
