PIR Motion Sensor - How it Works? How to use with Arduino?

The basic principle, when a human or warm-blooded animal comes to a radius of about 3 to 5 meters. This circuit detects infrared radiation from theirs and sends an output. When a signal from an Infrared PIR Sensor module comes to the Arduino Digital Pin 3. It is a 3V peak voltage. Then, this voltage flows to the Arduino Digital Pin 3 then Analysis the code  through Output Pin 13. It is good. Now we have a smart module. It has a delay time mode inside. But it may be expensive a little.

PIR Motion Sensor Side

The black wire is connected to the "gnd" pin.
The yellow wire is connected to the "out" pin.
The pink wire is connected to the "vcc" pin.

Arduino UNO Side

The black wire is connected to the "gnd" pin.
The yellow wire is connected to the "3 no" pin.
The pink wire is connected to the "vcc" pin.

To make this prototype I am using:-

Arduino UNO
PIR Motion Sensor
Jumper wire
