MR24HPB1 Fig.3 MR24HPB1 Diagram of the radar coverage area Due to the radar beam characteristics, the radar has a relatively long range in the direction normal to the antenna face, but a shorter range if it deviates from the antenna normal. When the radar is mounted on top or at an angle, the radar beam range and the effective radiation space will reduce the radar range, which needs to be taken into account when using the radar 4.2.

Installation Method The recommended mounting options for this radar module include horizontal, tilt and overhead mounting. 5.1.1. Horizontal Mounting As shown in Figure 4 for horizontal installation, this installation method is mainly orthogonal to human detection in a standing or sitting position, such as living rooms, home appliance applications and other occasions.
MR24HPB1 panels, screens and thin partition walls, and can detect moving objects behind obscurants; however, they cannot penetrate thicker load-bearing walls, metal doors, etc. Fig. 4 Schematic diagram of horizontal installation 5.1.2. Tilt Mounting The tilt installation is shown in Figure 5. This installation is mainly for detecting movement of people in the room and is mainly suitable for hotels, lobbies and other places. The radar installation height is recommended to be 2-2.
MR24HPB1 significantly compressed as the downward looking inclination angle increases. Due to the radiation characteristics of the radar antenna, the effective radar range is reduced by deviating from the position of the radar normal. Fig. 5 Diagram of the installation in oblique downward view. 5.1.3 Top Mounting A top-mounted installation is shown in Figure 4. This installation is mainly for human body monitoring in a lying position, such as bedrooms, elderly places, hospital beds, etc.
MR24HPB1 Due to the radar installation height and the radar beam range, the maximum distance for body movement detection in this installation mode is L3 ≈ 6.5m; the maximum distance for body sitting/ movement detection is L2 ≈ 3m and the maximum distance for body sleep detection is L1 ≈ 1.8m. Fig. 6 Diagram of installation in oblique downward view Caution. A.
MR24HPB1 D. Affected by the electromagnetic wave transmission characteristics, the radar action distance is related to the target RCS, target coverage material and thickness. D. Influenced by the electromagnetic wave transmission characteristics, the radar action distance is associated with the target RCS, target cover material and thickness, the effective radar action distance will change to a certain extent.

MR24HPB1 silent. B. radar from unmanned state to manned state (movement, approach, away) is a fast switching state, switching time ≤ 1s. C. Radar switching from manned state to unmanned state requires several state confirmations, with a switching time of ≥ 1 minute. 6. Typical Application Modes This module is mainly applied with home, home appliances, energy saving light control and other scenarios, the following application mode for typical scenarios is explained. 6.1.
MR24HPB1 6.2. Home Application For places such as homes, hotels, offices and bathrooms, there is a need for real-time detection of whether people are entering or whether people are moving in the place, which in turn enables ways such as security, electrical control and personnel monitoring, and can effectively avoid privacy issues.
MR24HPB1 6.4. Energy Saving Application Based on this radar motion target detection and biometric detection, the radar can have better applications in energy saving control, the main application modes are as follows: • Energy saving for home appliances • Energy saving controls for office appliances • Energy saving control for street lighting 7. Notes 7.1.
MR24HPB1 7.4. Power Radar modules require higher quality power supplies than conventional low frequency circuits. When supplying power to the module, the power supply must be free of threshold burr or ripple and effectively shielded from power supply noise caused by accessory equipment.
MR24HPB1 Semi-interference factors: Radar determines the presence of the human body and is not suitable for direct exposure to air conditioners. Internal motors in air conditioners can cause radar miscalculations. Radar products should not face the air conditioner directly. Or in the same direction as the air conditioner.
