Product Description
Occupancy detector with operating voltage of 12-24 V surface mounted detectors
MSA040D 99 is a 24GHz radar sensor based on Merrytek's patented orthogonal half-wave bending antenna. Its antenna has high gain and a wide detection range and is combined with Merrytek’s unique software algorithm. It can accurately detect minor movements brought by humans in almost all indoor spaces and provide fast and accurate front-end sensing input for smart home, smart hotel, smart office, and other scenes.

The sensor detects human walking, slight motion (such as body movement, turning the head, and other minor movements), and breathing to enable detection of human presence in non-sleep states.
- Movement signal: Large movements that trigger sensor activation within the detection area
- Slight motion signal: Very small movements including leaning forward, leaning back, body swinging, head shaking, typing, and mobile phone usage
- Breathing signal: Detection of breathing patterns through abdominal and chest cavity dilation
Dimensions (unit: mm)
Wiring Diagram
Detection Pattern
Important Notes:
- Detection range varies based on person size, material, covering thickness, and environmental factors
- Millimeter wave signals can penetrate non-metallic materials like glass and thin walls, but cannot penetrate thick load-bearing walls or metal doors
Remote Control (MH18 or MH10)
Initialization Process
When powered on, the sensor indicator will turn off after flashing for 20S and will not detect moving signals during this time. After 20S, you can use our MH10 or MH18 remote to adjust detection area, hold time, and daylight sensor, etc. parameters.
Factory Default Settings
- Detection Area: 4M Medium Sensitivity
- Hold Time: 30S
- Daylight Sensor: Disabled
- Indicator Light: Open

Application Guidelines
1. Sensor shall be installed and wired by a professional electrician
2. There shall be no high-power electrical appliance or high-power wireless device around our sensor to avoid interference and false triggers
3. Sensor clearance shall be longer than 2m if there are many sensors in your installation room
4. The sensor shall NOT be installed on shaking objects, and there shall be NO large metal, water pipeline, air draft, or ventilation system around our sensor to avoid interference and false triggers
5. There shall be NO strong lighting around our sensor to avoid daylight sensor false detection
6. The above sensor detection area data is based on 165cm high and 65kg heavy test people walking towards the sensor in a 41㎡ open area for your reference. When the sensor is installed in a different environment with a different test person, the real detection data might differ.
