Product Description

HC-SR505 Mini PIR Motion Sensor Module

Ultra-Compact Infrared Motion Detector for Arduino and Automatic Systems

The HCSR505 is a miniature PIR (Pyroelectric Infrared) motion sensor module designed for reliable human body detection in spaceconstrained and batterypowered projects. Its small footprint and low power consumption make it an ideal choice for Arduinobased automatic lighting, security, and sensing applications [citation:1][citation:2].

UltraCompact Size Measures only 10x23mm, fitting easily into small enclosures and portable devices [citation:1][citation:2].
Wide Operating Voltage Accepts 4.5V to 20V DC, compatible with 5V systems and batterypowered setups [citation:1][citation:2].
Supply Voltage Range: DC 4.5V to 20V. Output signal is 3.3V (HIGH) and 0V (LOW) [citation:1][citation:2].
Quiescent Current: Less than 60µA ideal for lowpower applications [citation:1][citation:2].
The module features a repeatable trigger. After initial activation, the delay timer resets with each new detection, keeping the output high while movement continues [citation:1][citation:2].

Use "technical">digitalRead() to read the sensor state (HIGH motion detected).
Allow a short startup period for the sensor to calibrate.
Avoid exposing the sensor to direct sunlight, heat sources, or strong air currents [citation:1].

Troubleshooting

Sensor not detecting motion:

  • Verify power supply is within 4.5V to 20V range [citation:1].
  • Ensure the sensor has passed its startup calibration period.
  • Avoid sources of infrared interference (direct sunlight, heat vents) [citation:1].

False triggers:

  • Check for vibrations or sudden temperature changes.
  • Ensure stable power supply (no ripples from motors or inductive loads).
  • Reduce sensitivity by adjusting the module or its placement.
