Human Body Induction Light on AliExpress 2026 - $3.18 Motion Sensor Night Light

How Human Body Induction Works
These lights use passive infrared (PIR) sensors to detect heat signatures from humans and animals within their range. When motion is detected within 8-16 feet (2-5 meters), the light activates.
Typical specifications:
- Detection range: 120° angle, 8-16 feet
- Light duration: 15-60 seconds (auto-off)
- Power: USB rechargeable or AAA batteries
- Luminance: 20-100 lumens

- Induction light (30 seconds x 20 uses/day): $0.003/month electricity
Even for hardwired versions, LED technology keeps power consumption minimal—typically 0.5-3W when active.
