Adjustable delay time: Flexible delay adjustment allows you to set the duration of device connection after the sensor no longer detects human presence, to meet different usage scenarios such as corridors, bathrooms, and offices. 50/60Hz wave human presence detection: Advanced millimeter wave radar technology can accurately detect real human presence, even when sitting or moving slightly, reducing false triggering compared to traditional PIR sensors. Wide voltage compatibility 100V-240V: Supports AC 100V-240V input, suitable for most household and commercial , and is an ideal choice for global smart living and home automation projects. Integrated light sensing function: The built-in light sensor automatically detects the ambient brightness and only triggers the load (such as the lamp) when the illumination is below the set level, which helps save and extend the life of the lamp. Smart living and home automation: designed specifically for modern smart homes, supporting use in corridors, stairs, bedrooms, kitchens, garages, and offices as part of intelligent lighting and security systems to enhance comfort and safety., Weight: 0.330693393 pounds, Manufacturer: Ehwisbe
