## Summary description

MACLEAN MCE323 is a microwave + PIR motion and twilight sensor designed for detecting movement and ambient light conditions. The sensor combines passive infrared and microwave technologies to improve presence detection and reduce false triggers. Intended for lighting control and basic automation tasks, it supports automatic on/off switching based on motion and dusk levels for energy-saving applications in homes and small commercial spaces.

## Long description

MACLEAN MCE323 is a compact motion and twilight sensor that combines passive infrared (PIR) and microwave detection to monitor presence and ambient light. Intended for simple lighting control and basic automation, the module activates outputs when it detects movement and can inhibit switching when ambient light exceeds a preset twilight threshold. Its small footprint allows installation in homes and small commercial spaces where reliable presence detection and energy-efficient lighting control are required.
Advantages
The dual-technology design reduces false triggers by requiring confirmation from microwave and PIR signals, increasing detection reliability compared with single-technology sensors. Integrated twilight sensing prevents lights from switching on during daylight, supporting energy savings. The compact form factor simplifies installation in ceilings, junction boxes, or behind fixtures where space is limited. The sensor’s responsiveness and combined detection methods make it suitable for varied indoor environments.
Suitable for
Automatic on/off lighting in corridors and stairwells
Energy-saving control in living rooms and bedrooms
Small offices and meeting rooms with intermittent occupancy
Utility areas such as storage rooms, pantries, and garages
Key specifications
Detection technologies: passive infrared (PIR) plus microwave
Functionality: motion detection and ambient light (twilight) sensing
Form factor: compact module suitable for recessed or concealed mounting
Intended application: indoor lighting control and basic automation
How to use
Install the MACLEAN MCE323 in a suitable ceiling opening, junction box, or behind a fixture according to the mounting space available. Position the sensor to cover the area where motion should be detected, avoiding direct exposure to heating vents or large reflective surfaces which can affect detection. Connect the module following electrical safety rules and local wiring standards; the sensor will switch lights on when motion is detected and allow lights to remain off when ambient light is above the twilight threshold.
Usage recommendations
For best performance, mount the sensor at the manufacturer’s recommended height and adjust placement so the detection zone covers primary traffic paths. Avoid mounting close to HVAC outlets or large glass surfaces. Use the twilight function to prevent unnecessary switching during daytime, and pair the sensor with appropriately rated lighting circuits and fixtures for reliable operation.
