YW101: ON/OFF Motion Sensor

Microwave Doppler Motion Detector Commercial Lighting Controls

The LITWHEAT Microwave Doppler Motion Detector is a high-sensitivity radar sensor module engineered specifically for modern commercial lighting controls. Utilizing the advanced Doppler effect, this detector emits low-power microwaves and analyzes the reflections to detect subtle human movements with exceptional precision, far surpassing traditional PIR sensors.

Designed for seamless integration into smart building systems, office spaces, and warehouse high-bay light fixtures, it reliably penetrates non-metallic materials (such as plastic, glass, and wooden doors) for concealed installation. Whether deployed for automatic dimming, daylight harvesting, or occupancy sensing, our microwave motion sensor ensures optimal energy efficiency and stable performance under diverse environmental conditions. We provide flexible OEM/ODM customization for global lighting manufacturers and system integrators.

>> Master/Slave Group Control (Corridor Function):

We offer a range of microwave motion detector designed to be built-in to luminaires for energy efficient lighting control. To switch ON/OFF AC mains automatically by human presence detection, the lights have the potential to achieve up to an 80% reduction in energy consumption. Options include ON/OFF microwave motion sensor, 0-10V dimming microwave sensor and wireless RF motion sensor.

Microwave motion detectors work by emitting microwaves and measuring the reflected wave to detect motion. The daylight threshold can be adjusted to a specific lux level, guaranteeing that luminaires only activate in conditions of dusk or darkness. Other parameter also can be set via DIP switch, like hold time, detection range, standby time, standby dimming etc.
