HLK-LD7901B 79G Water Level Detection Sensor LD7901B Millimeter Wave Radar Module Non-Contact(Without Cable)

HLK-LD7901B 79G Water Level Detection Sensor LD7901B Millimeter Wave Radar Module Non-Contact(Without Cable) Description

LD7901B is a 79GHz millimeter wave high frequency band radar sensor module. The working principle is to use FMCW FM continuous wave to convert water level into electric signal, which can realize effective water level measurement.
The product is mainly used for water level measurement in hydrological monitoring, urban pipe network and fire fighting water tank. Support UART output plug-and-play can be flexibly applied to different intelligent scenarios.
