HC SR501 PIR Motion Sensor

Description :

The HC-SR501 is a popular PIR (Passive Infrared) motion sensor module used for motion detection. PIR sensors are commonly used in various electronic projects, security systems, and automation applications. Here's some information about the HC-SR501 PIR motion sensor:

• The HC-SR501 uses a passive infrared sensor to detect changes in infrared radiation in its field of view.
• It doesn't emit any infrared radiation itself but rather detects changes in the heat radiation from the surrounding environment.

• When a person or an object with a different temperature than the surroundings moves into the sensor's field of view, it triggers the sensor.

Pin Configuration:

• VCC: Connect to a 5V power source.
• GND: Connect to ground.
• OUT: Digital output (high when motion is detected, low otherwise).
• Adjustment Trimmers: Used to set delay time and sensitivity.

 Usage:

• Connect VCC to 5V, GND to ground, and OUT to a digital input on a microcontroller or other digital circuit.
• Adjust the sensitivity and delay time using the trimmer potentiometers.

 Applications:

• Security systems.
• Lighting control.
• Automatic doors.
• Intruder detection.
• Home automation.
