MR24HPB1 Fig.3 MR24HPB1 Diagram of the radar coverage area Due to the characteristics of the radar’s beam, it has a long-range coverage in the direction normal to the antenna surface but a short-range if it deviates from the normal direction of the antenna surface. - Page 11 MR24HPB1 e. Early warning design function. 5. Works and Patterns 5.1. Installation Method There are three recommended installation methods for radar modules: horizontal, inclined, and overhead. 5.1.1. Horizontal Mounting Figure 4 shows the horizontal installation method. The method is primarily used to detect the presence of the human body in a standing or sitting position, such as in a living room, home appliance applications, and other situations.
- Page 12 MR24HPB1 Fig. 4 Schematic diagram of horizontal installation 5.1.2. Tilt Mounting Figure 5 illustrates an inclined installation. Generally, this installation method is intended to detect movement in a room and is primarily applicable to hotels, halls, and other public spaces.
- Page 13 MR24HPB1 Fig. 5 Diagram of the installation in oblique downward view. 5.1.3 Top Mounting Figure 4 illustrates how it is installed on top. This installation method is typically used to monitor human bodies (e.g. in a bedroom, nursing home, or hospital bed), determine fall hazards in wet and slippery environments, and to detect people who are asleep.
- Page 14 MR24HPB1 Fig. 6 Diagram of installation in oblique downward view Caution. A. In the various installation methods above, the radar's main beam should cover the human body's main activity area and face the normal direction as much as possible. B. When it is installed obliquely, the horizontal action distance will be correspondingly reduced due to the change in the horizontal projection of the coverage area.
- Page 15 MR24HPB1 ⦁ Status operation mode In this mode, the radar module periodically reports humans' presence and movement status in the current radar detection area. The main statuses include 1) unoccupied. 2) occupied, stationary. 3) occupied, active. During the status operation mode, the radar module performs internal logic discrimination to determine the environmental status's accuracy.
- Page 16 MR24HPB1 Radar is installed on the equipment in this scenario. As part of the routine operation of the equipment, the radar is installed horizontally or obliquely to guarantee that the radar beam covers the main work area. Conventional household appliances include •...
- Page 17 MR24HPB1 This mode can be used to implement a variety of applications, which include ⦁ Elderly care ⦁ Health care ⦁ Hotel applications ⦁ Home health 6.4. Energy-saving control applications The radar’s motion target and biometric detection capability enable it to have much better applications in energy-saving control.
- Page 18 MR24HPB1 7.2. Effective Detection Distance For the time being, this radar module does not feature a ranging function. Its range of detection is closely related to the RCS of the target and the environment in which it operates. Therefore, the effective detection range may change depending on the environment and the target.
- Page 19 MR24HPB1 Non-interference factors The radar's electromagnetic waves can penetrate human clothing, curtains, veneers, and glass. The installation angle and performance of the radar should be determined according to the intended use. Semi-interference factors The radar detects the presence of a human body, which is not ideal for facing the air conditioner directly.
