Frequently Asked Questions

Q: What type of bulbs is this PIR motion sensor switch compatible with?

A: This smart PIR motion sensor switch is designed specifically for LED lights with a maximum load power of ≤40W. It is not recommended for use with traditional incandescent or halogen bulbs above this wattage. Always ensure your bulb's wattage falls within the specified limit for safe and reliable operation.

Q: How do I adjust the time delay on the motion sensor switch?

A: The switch features an adjustable time delay setting, allowing you to control how long your lights remain on after motion is no longer detected. Simply turn the adjustment dial (where applicable) to your desired delay duration. This makes it highly adaptable for different rooms and usage scenarios.

Q: What is the ideal installation height and sensing range for this switch?

A: For optimal performance, the PIR motion sensor switch should be installed at a height of ≥3.5 metres. At this height, the sensor achieves its best detection range of 3–5 metres, ensuring wide and consistent coverage of the monitored area. The recommended installation hole size is φ20mm.

Q: Is this motion sensor switch suitable for outdoor use?

A: This switch is primarily designed for indoor use in locations such as hallways, stairwells, closets, and garages. For outdoor applications, ensure the installation environment is protected from direct exposure to rain and moisture, as the product specification does not indicate a weatherproof or IP-rated enclosure.
