Product description

The LD2410B is a highly sensitive 24GHz human presence sensing module. The working principle is to use FMCW FM continuous wave to detect the human body target in the set space, combined with radar signal processing accurate human body sensing algorithm, to achieve highly sensitive human presence state sensing, can identify the human body in motion and static state, and can calculate the distance of the target and other auxiliary information. The product is mainly used in indoor scenes, sensing whether there is movement or micromotion in the area, and real-time output results. The maximum sensing distance can reach 6 meters, and the resolution is 0.75m. The configuration tool is provided to configure the induction distance range, the induction sensitivity of different intervals and the unmanned delay time. Support GPIO and UART output, plug and play, can be flexibly applied to different intelligent scenarios and end products.

Product description

LD2410S is a low-power human presence detection millimeter wave radar sensor, hardware equipped with AloT millimeter wave sensor, high performance

24GHz transmit-receive antenna and peripheral circuit: Low power intelligent body sensing algorithm using millimeter wave sensor distance measurement technology and

The ICL1112 chip has proprietary radar signal processing and low-power control technology to achieve accurate perception of moving, micromoving and standing human bodies. Mainly used in indoor scenarios, it can sense whether there is a moving or twitching human body in the area in low-power mode, and refresh the detection results in real time. It can configure sensing distance range, trigger and hold thresholds of different intervals, data refresh rate under trigger and hold state, and unreported time, support GPIO and UART interfaces, plug and play, flexibly applied to different intelligent scenarios and terminal products.
