Product Description

How It Works:

Infrared Detection: The PIR sensor contains pyroelectric materials that detect infrared radiation. When a warm object, like a person or animal, moves within the sensor’s field of view, it changes the infrared radiation detected.
Signal Processing: The sensor processes this change and sends a digital signal to indicate motion.
Output Signal: The sensor typically provides a digital output, which goes high when motion is detected and returns to low after a set delay when no motion is detected.

Applications:

Security Systems: Commonly used in alarm systems to detect unauthorized entry.
Automatic Lighting: Used to automatically turn on lights when motion is detected in a room or outdoor area.
Smart Home Devices: Integrated into various home automation systems to activate cameras, alarms, or other devices.

Key Features:

Detection Range: Usually can detect motion within a range of 5 to 12 meters.
Field of View: Typically has a wide-angle field of view, around 110° to 180°.
Power: Operates at low voltage, often 5V or 12V, and is compatible with microcontrollers like Arduino or Raspberry Pi.
Adjustable Sensitivity and Time Delay: Many PIR sensors allow you to adjust sensitivity and the time the output signal stays high after motion is detected.

Advantages:

Low Power Consumption: Ideal for battery-powered devices.
Wide Range of Applications: Versatile and easy to integrate into various electronic projects.
Non-Intrusive: Detects motion without emitting any radiation, only sensing infrared radiation passively.

PIR motion sensors are popular in both commercial and DIY electronics for detecting the presence of people or animals.
