Description
The HKD Digital Passive Infrared (PIR) Motion Sensor, based on the popular HC-SR501 module, is a compact and highly effective motion detection unit designed for use in security systems, automation, and interactive electronics. This module detects infrared radiation emitted by moving human bodies within its field of view and provides a digital HIGH (3.3V) signal output when motion is detected.
With adjustable delay time and sensitivity settings, it is versatile and ideal for applications such as lighting automation, alarms, and motion-activated devices. The sensor supports a wide input voltage range from 5V to 20V, making it compatible with both 3.3V and 5V microcontrollers like Arduino, ESP32, and Raspberry Pi.
Key Features:
- Model: HC-SR501
- Detection Range: Adjustable from 3 to 7 meters
- Detection Angle: Approx. 120 (cone-shaped sensing area)
- Output Signal:
HIGH (3.3V) when motion is detected
LOW (0V) when idle - Delay Time: Adjustable from 5 seconds to 200 seconds
- Trigger Modes:
Non-repeatable trigger (once motion is detected, it will not re-trigger until the delay time elapses)
Repeatable trigger (continuously re-triggers as long as motion is detected) - Operating Voltage: 5V to 20V DC
- Board Dimensions: 32mm × 24mm
- Output Type: Digital (ON/OFF)
- Power Consumption: Low (ideal for battery-powered applications)
Applications:
- Security systems (motion detection alarms, surveillance triggers)
- Automatic lighting (motion-activated indoor/outdoor lights)
- Smart home automation (presence detection for energy-saving control)
- Industrial automation
- Consumer electronics (toys, interactive exhibits)
- Automatic control of appliances:
Lights, fans, buzzers, washing machines, dryers, etc. - Commercial and residential use:
Corridors, aisles, hotel rooms, stairways, restrooms, etc.
Advantages:
- Wide voltage compatibility for flexible power supply options
- Simple digital interface-ideal for direct connection to microcontroller GPIOs
- Adjustable detection parameters for fine-tuned performance
- Reliable detection for motion-triggered systems
- Compact and affordable, perfect for integration into custom enclosures
