PIR MOTION SENSOR FOR ARDUINO (ARD75E)

The HC-SR501 Passive Infrared (PIR) Motion Sensor detects movement by sensing changes in infrared radiation from people or animals. It is ideal for Arduino, ESP32, Raspberry Pi, and other microcontroller projects.

Features:

• Passive Infrared (PIR) motion detection
• Operating voltage: 4.5V–20V DC
• Digital HIGH/LOW output (3.3V HIGH)
• Adjustable detection distance: 3–7 m
• Detection angle: Up to 110°
• Adjustable output delay: 3 seconds to 5 minutes
• Repeatable (H) and Non-repeatable (L) trigger modes
• Low power consumption
• Warm-up time: 30–60 seconds

Pinout:

• VCC – 4.5V–20V DC
• OUT – Digital Output
• GND – Ground

Applications:

• Burglar alarms
• Automatic lighting
• Smart home automation
• Motion-activated switches
• Energy-saving lighting systems
• Robotics
• DIY and educational projects
