Hw-416-b Pir Sensor Datasheet

Enabling projects or mechanical props to "wake up" or interact when someone approaches. Troubleshooting False Triggers

If motion is detected continuously within the delay window, the internal timer resets, keeping the output HIGH until the target stops moving and the delay time elapses. 🔬 How the HW-416-B Works

| Feature | HW-416-B | HC-SR501 | |------------------|------------------|------------------| | Core chip | BIS0001 (or clone) | BIS0001 | | Voltage range | 4.5–20V | 5–20V | | Trigger modes | L / H jumper | L / H jumper | | Output voltage | 3.3V | 3.3V | | Availability | Lower cost, generic | Widely used | hw-416-b pir sensor datasheet

4.5V to 20V DC (typically powered via 5V) Static Current Consumption: < 60 µA Digital Output Level: High (3.3V) / Low (0V)

Decreases the output high duration (down to ~5 seconds). 3. Jumper Trigger Selection Enabling projects or mechanical props to "wake up"

The is a reliable, low-cost PIR motion sensor perfect for hobbyist and light commercial projects. While you won’t find an official “HW-416-B datasheet” from a major semiconductor brand, the HC-SR501 documentation applies directly . Use the specs and tips above to integrate it into your next motion-sensing project.

The following sketch reads the state of the HW-416-B sensor. It turns on the built-in Arduino LED (Pin 13) and prints alerts to the Serial Monitor when motion is detected.
