PIR Motion Sensor E27 Bulb Socket Adapter – Auto Light Switch
PIR Motion Sensor E27 Bulb Socket Adapter – Auto Light Switch
Smart PIR Motion Sensor E27 Lamp Base Holder with Auto Light Control
Upgrade any standard E27 bulb socket into a fully automatic, motion-activated lighting system. This intelligent PIR (Passive Infrared) induction bulb socket adapter detects human movement within its wide sensing range and instantly switches your light on — then automatically turns it off once the area is clear. Perfect for hands-free, energy-saving illumination wherever you need it.
Where Can You Use It?
- Stairways & hallways
- Fire escape and emergency passages
- Public walkways & corridors
- Garages, storage rooms & utility areas
- Security & deterrent lighting setups
- Any indoor location requiring hands-free automatic lighting
Key Features
- High-Sensitivity PIR Detection: Detects changes in the infrared spectrum generated by human movement. The light stays on while motion is present and automatically switches off once the area is clear — truly automatic "lights on when you arrive, lights off when you leave" convenience.
- Adjustable Delay Time: Choose from three preset delay segments — 17, 35, or 280 seconds — or fine-tune the delay continuously within the available range to suit your exact needs.
- Dual Control Modes: Factory set to activate only in low-light conditions (≤6 Lux), saving energy during daylight hours. Can also be switched to all-day sensing mode for round-the-clock operation.
- Wide Sensing Angle & Range: 138° cone detection angle with a sensing distance of up to 6 metres (±2 m) for broad, reliable coverage.
- Universal Voltage Compatibility: Works with AC 90–250V / 50–60Hz — suitable for use in both 110V and 240V electrical systems worldwide.
- Broad Bulb Compatibility: Supports LED, energy-saving, and incandescent bulbs up to 100W.
- Overload Protection: Built-in overload protection circuit for added safety during continuous use.
- Ultra-Low Standby Power: Static power consumption of just ≤0.012W — virtually zero energy wasted when idle.
- CE Certified for safety and electromagnetic compliance.

Installation & Safety Notes
- Always follow the wiring diagram printed on the back of the unit. Never exceed the rated load.
- Installation should be performed by a qualified electrician in accordance with local wiring regulations.
- Maintain a minimum distance of 0.5 m between the sensor socket and the bulb.
- Always switch off power before installing or wiring the device; energise only after installation is complete.
- If the bulb does not respond, verify the circuit connections and bulb condition first, then check the internal fuse of the socket.

Frequently Asked Questions
Q: What types of bulbs are compatible with this PIR motion sensor E27 socket adapter?
A: This E27 sensor socket adapter is compatible with LED bulbs, energy-saving compact fluorescent lamps (CFL), and traditional incandescent bulbs, supporting a load range of 1W up to 100W. Simply screw it into any standard E27 lamp fixture and insert your preferred bulb.
Q: Can I adjust how long the light stays on after motion is detected?
A: Yes! The delay time is fully adjustable. You can select from three colour-coded toggle positions: 17 seconds, 35 seconds, or 280 seconds. Additionally, within each delay range, the time can be fine-tuned continuously to your preferred duration. The factory default is approximately 40 seconds (±8 s).
Q: Will the motion sensor activate the light during the daytime?
A: By default, the sensor is factory-set to activate only when ambient light levels fall to 6 Lux or below — meaning it typically won't turn the light on in well-lit conditions, helping you save energy. If you prefer the sensor to respond to motion at any time of day, it can be switched to all-day sensing mode.
Q: Is this sensor socket compatible with both 110V and 240V electrical systems?
A: Yes. The adapter operates across a wide voltage range of AC 90–250V at 50/60Hz, making it suitable for electrical systems worldwide, including standard US 110V and European/Australian 220–240V systems.
