LD7901B 79G Non-Contact Water Level Detection Sensor Millimeter Wave Ra·DAR Sensing Module Support UART Output (Test Kit)

LD7901B 79G Non-Contact Water Level Detection Sensor Millimeter Wave Ra·dar Sensing Module Support UART Output Product Description LD7901B is a ra·dar sensing module using 79GHz millimeter wave high frequency band. The working principle is to use FMCW FM continuous wave to convert the water level into an electrical signal, which can realize the effective measurement of water level. The product is mainly used for water level measurement in hydrological monitoring, urban pipeline network and fire-fighting water tanks. Support UART output. Plug and play, can be flexibly applied to different intelligent scenes.
