24GHz HLK-LD2410S Sensor 0.1mA 3.3V Low power consumption Millimeter Wave Human Presence Motion Switch LD2410S

Welcome to HI-LINK store!

1. Introduction

HLK-LD2410Sis a battery-powered, ul-low-power human presence millimetre wave sensor of the HLK- LD2410S series, containing the extremely simplified24GHz millimetre wave sensorhardware LD2410S and the low-power human presence sensing smart algorithm .

The hardware LD2410S is equipped with an AIoT millimetre wave sensor, a high-performance 24GHz one-nsmitter-one-receiver and peripheral circuits; the low-power intelligent human presence sensing algorithm adopts the millimetre-wave sensor distance measurement technology and the ICL1112 chip's advanced proprietary signal proceing and low-power control technology to achieve the accurate sensing of motion, micro-motion and standing human bodies. The low-power human presence sensing algorithm is mainly applied in indoor scenes, sensing whether there is a moving or micro-moving human body in the area in low-power mode, and refreshing the results in real time.

5. Installation and range

The recommended mounting method for the HLK-LD2410S is wall mounting. For wall mounting, the orientation of the millimetre wave sensor is shown in Figure 6-1. Where the X-axis direction is 0°, the Z-axis direction is 90°, and the Y-axis is perpendicular to the X-Z plane (also called the normal direction).

Figure 6-1 Sensor Orientation Schematic

The recommended wall mounting height is 1.5~2 m. In this case, the maximum motion sensing range of HLK-LD2410S in the default configuration is a conical space with a normal direction of 8 m and a horizontal and pitch angle of ±60°, as shown in Figure 6-2.

Figure 6-2 HLK-LD2410S Schematic diagram of range (wall-mounted)

At a wall mounting height of 1.5 m, the range of HLK-LD2410S for stationary, slightly moving and moving human body in all directions is shown in Figure 6-3.
