IR24VDA 5. 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.
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.
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.).
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.
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.
IR24VDA 6.2. Application in Smart Home For homes, hotels, offices, toilets and other places, it is necessary to detect whether there are people entering or moving in the place in real time, so as to realize methods such as security, electrical control and personnel monitoring, and effectively avoid privacy problems. The radar is installed in the room and can monitor whether there are moving targets, personnel movement direction and personnel in the room in real time.
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.
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.
