The DC 12V 5A IR Pyroelectric Infrared (PIR) Motion Sensor Detector Module is an electronic device that is used to detect motion, specifically human or animal movement, within its field of view. PIR sensors are commonly used in security systems, lighting control, and various automation applications.
Detection Range: PIR sensors have a specific detection range and field of view. When a person or object moves within this area, the sensor detects the change in infrared radiation emitted by the moving object.
Sensitivity Adjustment: Many PIR sensor modules come with a sensitivity adjustment potentiometer that allows you to set the detection sensitivity to match your application's requirements. You can adjust the sensitivity to make the sensor more or less responsive to motion.
Time Delay Adjustment: Some PIR modules also include a time delay adjustment potentiometer. This setting determines how long the sensor's output remains active (high) after detecting motion. It can be adjusted to control how long a connected device (e.g., a light) stays on after motion is detected.
Output: The module typically provides an output signal that changes when motion is detected. This output is often in the form of a digital signal (high/low), making it easy to interface with microcontrollers, relays, or other control circuits.
Lighting Control: To automatically turn on lights when motion is detected and turn them off when no motion is detected (energy-saving).
Home Automation: As part of home automation systems for controlling appliances, HVAC systems, or other devices based on occupancy.
Outdoor Lighting: For controlling outdoor lighting, especially in response to approaching pedestrians or vehicles.
Industrial Automation: In industrial settings to control machinery or equipment based on the presence of workers.
Key Features:
Power Supply: The module requires a DC power supply voltage of 12V and can typically handle a current of up to 5A. This voltage is used to power the internal circuitry of the PIR sensor.Detection Range: PIR sensors have a specific detection range and field of view. When a person or object moves within this area, the sensor detects the change in infrared radiation emitted by the moving object.
Sensitivity Adjustment: Many PIR sensor modules come with a sensitivity adjustment potentiometer that allows you to set the detection sensitivity to match your application's requirements. You can adjust the sensitivity to make the sensor more or less responsive to motion.

Applications:
Security Systems: To trigger alarms or surveillance cameras when motion is detected.Lighting Control: To automatically turn on lights when motion is detected and turn them off when no motion is detected (energy-saving).
Home Automation: As part of home automation systems for controlling appliances, HVAC systems, or other devices based on occupancy.
Outdoor Lighting: For controlling outdoor lighting, especially in response to approaching pedestrians or vehicles.
