Hw416b Pir Sensor Datasheet Better Info

If you need performance instead of guessing HW416B’s specs, use:

| Parameter | Value | Notes | | :--- | :--- | :--- | | | DC 5V – 20V | Optimal performance at 5V or 12V | | Static Current | < 50 µA | Ultra-low power for battery applications | | Output Signal | 3.3V TTL (HIGH / LOW) | Compatible with 5V microcontrollers (3.3V logic is safe for 5V pins via voltage divider) | | Detection Angle | < 120° (cone shape) | Adjustable via lens masking | | Detection Distance | 3 – 7 meters (adjustable) | Factory default: ~5 meters | | Time Delay Adjust | 0.3 sec – 5 minutes (variable) | Two potentiometers control this | | Trigger Modes | Single (non-repeatable) / Repeatable (retriggering) | Jumper-selectable | | Operating Temperature | -15°C to +70°C | Reduced sensitivity in extreme cold | | Lens Type | Fresnel lens (white/translucent) | Included on top of the pyroelectric element | hw416b pir sensor datasheet better

Because the HW-416B can give false triggers on power-up, use this code instead of the basic "Blink" sketch: If you need performance instead of guessing HW416B’s

Unlike some "mini" PIR sensors that have fixed settings, the HW-416B usually features two potentiometers (or specific solder pads) that allow for: hw416b pir sensor datasheet better
