MSA246S 99 V is a 24GHz radar sensor based on Merrytek's patented orthogonal antenna. Its antenna has high gain and a wide detection range. Combined with Merrytek’s unique software algorithm and FMCW modulation, it can accurately detect micro-movements brought by humans in almost all indoor spaces to automatically turn on or turn off lighting, etc electrical appliances.

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.
When powered on, the sensor indicator will turn off after flashing for 10S and will enter a 10S detection cycle. If presence is detected, then the sensor will report presence and enter hold time calculation; if absence is detected, then the sensor will report absence. During initialization, the sensor will not detect a moving signal, and you can use our MH10/MH18 remote or rotation switch to adjust detection area, hold time, and daylight sensor, etc. parameters.

*When set to disable, our sensor will turn on the light when motion is detected, regardless of the environment's daylight
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.
