Arduino Compatible PIR Motion Detector Module

A pyroelectric infrared (PIR) motion sensor module for Arduino and microcontroller projects. It detects movement from people and animals by sensing changes in infrared radiation, outputting a digital high signal when motion is detected. Two onboard potentiometers allow adjustment of sensitivity and delay time.

Key Features

• PIR Motion Detection – Detects movement via infrared radiation changes
• Adjustable Sensitivity – Onboard potentiometer to tune detection range
• Adjustable Delay Time – 0.3–18 seconds output hold time via potentiometer
• Digital Output – High (3V) when motion detected, low (0V) when idle
• Wide Voltage Range – 5–20V supply for flexible integration
• Ultra-Low Standby Current – Just 65μA quiescent draw

Specifications

• Output: Digital (3V high / 0V low)
• Delay Time: 0.3–18 seconds (adjustable)
• Quiescent Current: 65μA
