The product is mainly used in home, office, public places and other scenes. The following is an
explanation of the application mode for typical scenes.
In today's era, smart home is in the ascendant. It is a major topics of smart home that carrying out system management based on the human-existing in the home place makes all home units, such as lighting, home appliances, electric control, temperature control, fresh air and other systems runs intelligently with human center.
Merrytek MSA202S RC detects human moving signals by 24GHz millimeter wave, it can cooperate with various systems of the home to achieve the ultimate home experience where people go, the light moves with it, and the temperature is comfortable.
Scenes: kitchen, cloakroom, living room and bathroom
In view of the increasing demand for energy consumption in office spaces, more and more users are looking for humanized automatic dimming and switching of lamps in offices, conference rooms, bathrooms and other scenes.
Humanized automatic air conditioning and air volume adjustment are used to take into account the needs of healthy office and energy saving and emission reduction.
This sensor can accurately output human-existing/no-human signals to match with sensors such as temperature, humidity, and illumination, which perfectly meets the user's human-oriented intelligent application in the office.

It can effectively meet the needs of the hotel based on human-existing for intelligent electricity, intelligent fresh air and intelligent bathroom.
Scenes: card-free power extraction, scene interaction, Smart bathroom, hotel electrical energy saving, human-existing/ no-human monitoring
Walk Mode
a large movement (walking) of the human body.
Leisure Mode
only small motion of the human body, such as: forward, backward, limb swing, head shaking, typing, playing with mobile phones and other minor actions.
Presence Mode
only detects human breathing within 30S (abdominal cavity, thoracic cavity expansion behavior actions), no significant movement is detected.
The product detects human moving, minor moving, and presence signals, and realizes the detection of human-existing/no-human in non-sleep state. The following is a description of the moving, minor moving and presence signals:
- Moving signal: detect the human significant moving (walking) in the detection area.
- Minor moving signal: detect the human slight moving in the detection area, such as leaning forward,
leaning forwarder and back, swinging limbs, shaking head, typing, playing with mobile phones and so on.
- Presence signal: detect human abdominal and thoracic expansion behaviors caused by breathing, but not detect moving signal and minor moving signal.
1. Product should be installed by a professional electrician.
2. Product should be kept as far away as possible from large-area metal plates, glass and other substances with high medium density to avoid false triggering.
3. The antenna surface of the product and its nearby circuits should avoid the flow of large currents, so as not to affect the normal operation of the product.
4. When installing multiple products in one place, please try to ensure that the antenna surfaces of the products are parallel to each other and do not face each other. The installation distance between products should be greater than 1m. Dense installation may cause false reports.
5. The antenna surface of the product should avoid facing the AC drive power supply, and stay away from the rectifier bridge, transformer, switch tube and other high-power devices of the drive power supply, so as to avoid power frequency signals from interfering with the microwave module.
6. Avoid using objects that vibrate for a long time around the product, such as shaking head fans and so on. The vibration signal will be regarded as a moving signal to trigger the product.
7. Avoid unnecessary lights illuminating the product's illuminance sensor detection window and interfere with the measurement of ambient light.
8. The microwave sensor has an ability to penetrate the building wall, and the microwave that penetrates outside the wall may cause false triggering when it detects moving objects. In order to avoid false triggering, when installing, please choose appropriate detection area, for example:
8.1 When product is used in the room whose length and width is about 2m or less, detection area should be set to 25%(application scenes: washroom, sitting room );
8.2 When product is used in the room whose length and width is about 3m, detection area should be set to 50%(application scenes: washroom, hallway, sitting room );
8.3 When product is used in the room whose length and width is about 4m, detection area should be set to 75%(application scenes: small office, meeting room, library );
8.4 When product is used in the room whose length and width is about 5m or more, detection area should be set to 100%(application scenes: large office, meeting room, library ).
Note: The setting detection area depends on the actual environment( detection area parameters above application scenes are for reference only).
9.The detection distance is related to the moving speed of the moving object, the size of the moving object, the installation height, the installation angle, whether the installation environment is empty, the material of the reflector and other factors. The detection distances given in the specification are typical values, which are obtained by testers at height of 165cm and weight of 65kg and tested in an indoor open environment.
10.Product specifications and parameters may be optimized without prior notice.
