The HW-416-B is notably smaller than the HC-SR501. Its compact form factor makes it ideal for wearable tech or small enclosure projects.
, offering tight component tolerances for stable performance in varying temperatures. Specification DC 4.5V – 20V Static Current Output Level 3.3V (High) / 0V (Low) Detection Range Adjustable from 3m to 7m Detection Angle < 120° cone angle Delay Time Adjustable (approx. 0.3s to 5 minutes) Operating Temp -20°C to +80°C Pinout & Wiring HC-SR501 PIR MOTION DETECTOR hw-416-b pir sensor datasheet
Note: Lockout time (approx 2 seconds) after OUT goes LOW – sensor ignores motion to prevent oscillation. The HW-416-B is notably smaller than the HC-SR501
If you’re building a motion-activated light, security alarm, or smart occupancy sensor, you’ve likely come across the . At first glance, it looks identical to the famous HC-SR501. In fact, for practical purposes, the HW-416-B shares the same core components: a Pyroelectric Infrared (PIR) sensor , a BIS0001 (or similar) signal processing IC, and an adjustable lens. Specification DC 4
⚠️ The HW-416-B uses two potentiometers. On some boards, the left is SENS and right is TIME . Verify with your specific board silkscreen or by testing.
