LD2413 is a 24GHz millimeter wave band radar module equipped with AIOT millimeter wave sensor chip, high performance one-transmitter-one-receiver microstrip antenna, MCU and external auxiliary circuits. Highly accurate liquid/ material level detection intelligent algorithm, using FMCW waveforms and the chip's proprietary advanced radar signal processing, to achieve accurate detection of the height of liquids and materials. The product is mainly used in hydrological monitoring, urban pipeline network, water level measurement in fire-fighting water tanks. Support UART output, plug and play, can be flexibly applied to different intelligent scenes.
