IR24BDA 5. Installation Method and Operating Mode 5.1. Installation Method It is recommended to install the radar module according to the specific functions. 5.1.1 Respiration Rate Statistics BE 5.1.2 Sleep Quality Evaluation L For this function, it is necessary to keep the position between the radar and the chest within the range of 0.5m-1.5m, and expose the chest within the detection range of the radar antenna.
IR24BDA 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 Operating Mode In this mode, the radar module periodically gives the existence status and movement status of personnel in the current radar detection area.
IR24BDA E. When it is necessary to use the sleep quality assessment and sleep time recording functions of the sleep detection radar, the installation method can only be top mounted or inclined. The radar installation height is not higher than 2.75m. The installation scene is only suitable for rest areas such as the bed top of the bedroom 6. Typical Application Mode BE L This module is mainly used in home, home appliances, energy-saving lamp control and other scenarios.
IR24BDA 6.2. Application in Home This radar can be applied into following scenes： ◆ Household security BE ◆ Hotel management and monitoring L 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.

IR24BDA 7.2. Effective detection distance 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 fluctuate within a certain range. L 7.3.
IR24BDA 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. L Non-interference factors: Radar electromagnetic waves can penetrate human clothing, curtains, veneer, and glass.
