HLK-LD2410S Microamp Low Power Radar Sensing Module
Product Link
Description
LD2410S is an ultra-low-power human presence millimetre wave sensor, including extremely simplified 24GHz millimetre wave sensor hardware and low-power human presence sensing intelligent algorithm firmware.
The hardware is equipped with an AIoT millimetre wave sensor, a high-performance 24GHz one-transmitter-one-receiver antenna 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 radar signal processing and low-power control technology to achieve the precise sensing of motion, micro-motion and standing human bodies. The product is mainly used in indoor scenarios, sensing whether there is a moving or slightly moving human body in the area in low-power mode, and refreshing the detection results in real time.
The maximum sensing distance of moving human body is 8m, the trigger and hold thresholds of different zones, the human body presence status and target human body distance reporting frequency, as well as the unoccupied reporting time. Support GPIO and UART interface, plug and play, flexible application in different intelligent scenes and terminal products.
