PIR Sensor Detecting Object Using Arduino

Introduction

• It is used to detect the human being moving around approximately 10m from sensor.
• The actual range is between 5m to 12m.
• It is of high sensitivity and low noise.

• Arduino Board
• PIR Sensor
• Buzzer
• Bread Board
• LED
• Hookup wire

• In the PIR sensor, they have three pins.
• The first pin can be connected to dc voltage range as 5v.
• The second pin can be connected to the Arduino board 5 in digital pin.

• The anode(+) pin can be connected to the digital pin 7 to an Arduino board.
• The cathode(-) pin can be connected to the Gnd to an Arduino board.

• The red color wire can be connected to the digital pin 10 to the Arduino board.
• The black color wire can be connected to the Gnd to the Arduino board.
• We can connect both the wires in exchange.
