Installation and Operating Mode 5.1. Installation It is recommended to install the radar module in horizontal-mounted, inclined-mounted and top-mounted. 5.1.1. Horizontal-mounted As shown in Figure 4, it is a horizontal installation mode. This installation mode is mainly aimed at human body detection in standing or sitting posture, such as living room, home appliance application and other occasions. The radar installation height is recommended to be 1m ~ 1.5. The radar is installed horizontally and forward, the installation inclination is ± 5°, and there is no obvious shelter and cover in front. L The normal direction of the radar is aligned with the main detection position to ensure that the main beam of the radar antenna covers the detection area and E the radar beam covers the airspace of human activities. In this installation mode, the maximum detection distance of moving human B body is L3 13m, the maximum detection distance of human sitting / slight motion is L2 5m. A Limited by the beam range of the radar antenna, the effective range will be reduced if it deviates from the normal direction of the radar. Millimeter wave band electromagnetic wave has certain penetration characteristics for non-metallic L materials, can penetrate common glass, wood, screen and thin partition wall, and can detect moving objects behind the shelter; However, it cannot penetrate IF thick bearing walls and metal doors. www.iflabel.com Figure 4. Horizontal-mounted 1118 IR24VDA 5.1.2. Inclined-mounted As shown in Figure 5, it is installed obliquely. The installation method mainly detects the movement of people in the room, which is suitable for hotels, halls and other places. The recommended installation height of radar is 2-2.75m; The downward looking tilt angle range of the radar is 10 ° ~ 30 °, and there is no obvious shelter and cover in front of the radar. The normal direction of the radar is aligned with the main detection position to ensure that the main beam of the radar antenna covers the detection area and the radar beam covers the airspace of human activities. L In this installation mode, the maximum detection distance of moving human body is L3 7m; The maximum distance of human sitting /slight motion detection E is L2 4m. In this mode, there may be a surveillance blind area directly below the radar and B adjacent areas. With the increase of downward viewing angle, the detection distance of stationary human body will be significantly compressed. A Affected by the radiation characteristics of radar antenna, the effective range of IFL radar will be reduced if it deviates from the normal direction of radar. Figure 5. Inclined-mounted www.iflabel.com 1218 IR24VDA 5.1.3. Top-mounted As shown in Figure 4, it is installed on the top. This installation method is mainly aimed at slippery areas where there is a risk of falling (e.g. toilet, kitchen, etc.) human body monitoring under peaceful lying state (e.g. bedroom, nursing place, hospital bed, etc.). The radar shall be installed vertically, and the horizontal deviation angle shall be 3 °, so as to ensure that the main beam of the radar covers the detection area; The recommended installation height of radar is 2.75m; There is no obvious shelter or cover in front of the radar. Affected by the radar installation height and radar beam range, in this installation mode, the maximum detection distance of active human body is L3 6.5m; The maximum distance of human sitting / slight motion detection is L2 3M. A BEL Triggered by Movement Keep Stationary/Slight Motion Sleep Perception Figure 6. Top-mounted L Note IF A. For the above different installation methods, the main radar beam needs to cover the main activity area of the human body and face the normal direction as far as possible B. When installed obliquely, the horizontal action distance will be reduced due to the change of horizontal projection of the coverage area C. When the module is working, the module surface should not be covered by metal objects D. Affected by the transmission characteristics of electromagnetic wave, the radar range is related to the target RCS, the material and thickness of the target cover. The effective range of radar will change to a certain extent; www.iflabel.com 1318 IR24VDA E. Corresponding to human body detection in st at ionary state, different body positions will affect the radar range, and the radar does not guarantee that all states reach the maximum range. 5.2. Operating Mode After statistical analysis and processing, the radar module comprehensively evaluates the personnel status in the current detection area, and the user can directly use the results. State Modes In this mode, the radar module periodically gives the existence status and movement status of personnel in the current radar detection area. The main states include: 1) Nobody L 2)Somebody, stationary 3)Somebody, active E In the state operation mode, in order to judge the accuracy of environmental state, logic discrimination is carried out inside the radar module. B The state output logic of the radar module is as follows: A. Only when the radar equipment detects the state change can the radar have the corresponding state output; On the contrary, the radar remains A silent B. When the radar make quick switches from nobody state to somebody state, L shift Time1s C. When the radar switches from somebody state to nobody state, it needs IF to be confirmed for many times, and the switching time is 1 minute www.iflabel.com 1418 IR24VDA 6. Typical Application Mode This module is mainly used in home, home appliances, energy-saving light control, health care and other scenarios. The application modes of typical scenarios are described below. 6.1. Application in Smart Appliances The radar is installed inside the home appliance equipment and monitors the personnel status of the home appliance equipment working face in real time. The equipment adjusts the equipment working mode (working, low power consumption, standby, shutdown, etc.) in real time or quasi real time according to the personnel status of the working face (manned / unmanned, active / stationary, close / far away), so as to realize the intellectualization of household appliances. In this application scenario, the radar is installed on the equipment radar. According to the conventional nature of the equipment, the radar is installed L horizontally or obliquely to ensure that the radar beam can cover the main working area of the equipment. E Regular Home Appliances include Smart TV Smart Voice Box B Smart Air-conditioner IFLA Other smart home appliances www.iflabel.com 1518 IR24VDA 6.2.

The main application modes are as follows Energy-saving Control of Household Appliances Energy-saving Control of Office Appliances Energy-saving Control of Street Lamps www.iflabel.com 1618 IR24VDA 7. Precautions 7.1. Start Time When the module starts to work when it is initially powered on, it is necessary to completely reset the internal circuit of the module and fully evaluate the environmental noise to ensure the normal operation of the module. Therefore, when the module is initially powered on, it needs a startup stability time of 30s to ensure the validity of subsequent output parameters. 7.2. Effective Detection Range The detection range of the radar module is greatly related to the target RCS and environmental factors. The effective detection range may change with changes in the environment and the target. This module does not have a ranging function for the time being, so it is normal for the effective detection range to L fluctuate within a certain range. 7.3. Radar Biological Detection Performance E Because human biological characteristics belong to ultra-low frequency band weak reflection characteristic signals, radar processing requires a relatively long cumulative processing. During the cumulative process, many factors may B affect the radar parameters, so occasional detection failure is normal. 7.4. Power Supply A The radar module requires higher power quality than conventional low frequency circuits. When powering the module, it is required that the power L supply has no threshold glitches or ripples and that it effectively shields the power supply noise caused by accessory equipment. The radar module needs to be well grounded. Due to the ground noise IF brought by other circuits, the performance of the radar module may even be reduced or even work abnormally; the most common cause is a shorter detection distance or an increased false alarm rate. In order to ensure the normal operation of the VCO circuit inside the module, the power supply requirement for this module is + 5V- + 6V power supply, voltage ripple50mV. The external power supply must provide sufficient current output capability and transient response capability www.iflabel.com 1718 IR24VDA 8. FAQ Interference factors: Radar is an electromagnetic wave detection sensor, and active non-living objects will cause false alarms. The movement of metals and liquids can cause misjudgments. Usually, electric fans, pets close to the radar, and the shaking of metal curtains will cause misjudgments. Radar needs to be planned from the perspective of installation. Non-interference factors: Radar electromagnetic waves can penetrate human clothing, curtains, veneer, and glass. It is necessary to determine the installation angle and performance of the radar according to the application. Semi-interference factor: The radar judges the presence of a human body L and is not suitable for directly facing the air conditioner. The motor inside the air conditioner can cause the radar to misjudge. Radar products can not E directly face the air conditioner. It can be the same direction as the air conditioner. 9.
