Hw416b Pir Sensor Datasheet Better May 2026

HW-416B PIR sensor is a high-performance passive infrared motion detector widely recognized as a reliable alternative to the industry-standard HC-SR501

• Fully counter-clockwise (CW min): ~0.3 seconds
• Fully clockwise (CW max): ~300 seconds (5 minutes)

✅ HC-SR501 Datasheet – What it includes

• Operating voltage: DC 5V–20V
• Quiescent current: <50µA
• Output: HIGH 3.3V / LOW 0V
• Delay time: 5–300 sec (adjustable)
• Trigger modes: single / repeatable (jumper select)
• Detection range: up to 7m, 120° cone
• Operating temperature: -15°C to +70°C

• Low current (1µA – 6µA)
• Complete datasheet (sensitivity, lens options, timing, noise)
• Example: EKMB1193111

HW416B OUT → 1kΩ resistor → Base of BC547
Emitter of BC547 → GND
Collector → Relay coil negative terminal
Relay coil positive → VCC (with flyback diode)

Review: Compact PIR Motion Sensor Modules (HW416B / Generic Mini PIR)

The Verdict Upfront

If the "HW416B" is the compact, dome-topped sensor often sold in multi-packs, it is significantly better for finished projects but worse for breadboard prototyping compared to the standard HC-SR501. It excels in aesthetics and size but lacks the manual adjustment flexibility of larger sensors. hw416b pir sensor datasheet better
