Motion Detection & Switching Sensor Module (MR-HW08KT)
Automate your space and cut down energy costs effortlessly with the MR-HW08KT PIR Motion Detection and Switching Sensor Module. This compact, highly reliable module connects directly to your standard 220V–240V AC mains supply, completely removing the need for external DC power adapters.
Engineered with advanced Passive Infrared (PIR) technology, it automatically triggers connected appliances—such as LED downlights, exhaust fans, or passageway bulbs—whenever human movement is detected. Featuring built-in manual selectors for both time duration and light sensitivity (LUX), it offers customized, hands-free automation for smart homes, retail spaces, and industrial walkways.
Key Features
Direct Mains Operation: Engineered to run directly on standard 220V–240V AC lines, simplifying installation wiring for electricians and DIY builders alike.
Onboard Adjustments: Features easy-to-configure physical switches to set your preferred operational timing cycles and ambient daylight thresholds.
Smart Day/Night Detection: Includes an adjustable light sensor (LUX) so you can program the module to trigger load only in total darkness, low ambient light, or continuously through day and night.
Ultra-Low Idle Power: Runs highly efficiently, drawing less than 0.1W during standby mode to maximize long-term energy savings.
Recessed Mini Form Factor: Requires a tiny 26mm cut-out hole size, allowing the module to sit completely flush inside ceilings, custom switch plate panels, cabinet frames, or wall mounts.

Hardware Adjustment Layout
The module is designed for precise configuration via toggle selectors located directly on its compact frame:
Time Delay Settings: Quickly calibrate how long your load stays active after movement stops. Options include a quick pulse (15 seconds), mid-range lighting (45 seconds), or room clearance (5 minutes).
LUX Light Sensor Tuning:
Deep Dark (2 Lux): Only triggers when the environment is completely dark (e.g., night-time bathroom or corridor security).
Light Dark (25 Lux): Triggers during low-light/twilight conditions (e.g., early morning/evening hallways).
Disable: The sensor triggers on motion regardless of whether it is broad daylight or nighttime.
Common Applications
Smart Home Convenience: Automate lighting inside modern walk-in wardrobes, staircase paths, bathrooms, and kitchen cabinets.
Commercial Spaces: Hands-free lighting control for office hallways, public restrooms, and store utility closets.
Energy Management: Automatically shuts off exhaust ventilation or walkway illumination when rooms are left unoccupied.
Safety Warning: This module hooks up directly to a high-voltage 220V AC mains line. To prevent risk of shock or equipment damage, please ensure the main electrical breaker is completely turned off prior to stripping or installing the load wiring.
