Hw-416-b Pir Sensor Datasheet Here

A Passive Infrared (PIR) sensor measures infrared light radiating from objects in its field of view. The HW-416-B operates by detecting the thermal changes caused by moving human bodies or animals. It features a specialized Fresnel lens that focuses infrared radiation onto the internal pyroelectric sensor. 2. Technical Specifications Typical Value 4.5V to 20V DC Output Level High: 3.3V / Low: 0V Quiescent Current Approximately Detection Distance Up to 7 meters (adjustable via potentiometer) Detection Angle Delay Time 5s to 200s (adjustable) Blockade Time 2.5s (default) Trigger Method L (non-repeatable) / H (repeatable) Operating Temperature 3. Pin Configuration

The is a high-performance passive infrared (PIR) motion sensor module, frequently used as a direct, reliable replacement for the standard HC-SR501 . It detects human and animal movement by sensing changes in infrared radiation emitted by warm objects. Core Specifications is electrically and physically identical to the Go to product viewer dialog for this item. hw-416-b pir sensor datasheet
