Hw-416-b Pir Sensor Datasheet

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

Supply voltage: 4.5V to 20V DC. Output voltage: 3.3V HIGH / 0V LOW (compatible with 3.3V and 5V microcontrollers) Detection range:

| Jumper Setting | Mode | Behavior | |----------------|------|----------| | (Repeatable) | Repeat trigger | Output remains HIGH as long as motion continues. Additional triggers during the delay period extend the output HIGH time. Ideal for continuous detection applications. | | L (Non-repeatable) | Single trigger | Output goes HIGH once upon motion detection and will not retrigger during the output delay period. The sensor “locks out” until the delay expires. | hw-416-b pir sensor datasheet

The PCB is double-layered with a ground plane to reduce noise. The FR-4 material ensures decent thermal stability, though prolonged exposure to direct sunlight or heat sources can trigger false positives (a common trait of all PIR sensors).

Comprehensive Guide to the HW-416-B PIR Motion Sensor The is a compact, highly efficient Passive Infrared (PIR) sensor module widely used in DIY electronics, security systems, and automated lighting projects . Often categorized alongside the popular HC-SR501, the HW-416-B is favored for its smaller footprint and reliable performance in detecting human or animal movement. Output voltage: 3

Are you triggering a specific ? (like a relay , buzzer , or smart home automation event )

When motion is detected, the output goes HIGH. If the target keeps moving within the detection area before the delay time expires, the timer resets, keeping the output HIGH continuously until the target leaves. Interfacing HW-416-B with Arduino
