HC-SR505 Mini Infrared PIR Motion Sensor Module

The HC-SR505 is a miniaturized PIR (Passive Infrared) motion sensor module that is designed with a high degree of sensitivity for a wide range of automatic control applications. It leverages infrared technology, operates at an ultra-low voltage, and is perfectly suited for devices powered by batteries. The module offers a high level of reliability and precision in detecting motion.

Technical Specifications

• Operating Voltage Range: DC 4.5V – 20V
• Static Current: Less than 60μA
• Output Level: High 3.3V / Low 0V
• Trigger: Repeatable trigger (default)
• Delay Time: Default 8 seconds ± 30% (can be customized)
• PCB Size: 10mm x 23mm
• Induction Angle: Less than 100-degree cone
• Induction Distance: Up to 3 meters
• Working Temperature: -20°C to +80°C

Key Features

• Automatic Induction: The sensor outputs a high signal when a person enters its detection range and reverts to a low signal after the default delay once the person exits the range. The sensor is ultra-compact in size.
• Repeatable Triggering: If continuous motion is detected within the sensor's range, the output remains high. The output only reverts to low after the delay period when no further motion is detected.
• Wide Operating Voltage Range: The sensor operates within a DC 4.5V – 20V range.
• Low Power Consumption: The working current is less than 50μA, making it ideal for battery-powered automatic control applications.
• Output Signal: The sensor provides a high output signal that can be easily integrated with various circuits.
