The Laser Depth Sensor (LDS01) measures either depth or height of a material such as snow, a river level or a tank of liquid. Using either an Ecowitt gateway, you can upload data to the Ecowitt network to view a history of level data or view live on the supported consoles.

The sensor transmits an average reading every 60 seconds, unless a rapid change in level is detected, such as rising river level or tank leak, then this increases to every 10 seconds.

The LDS01 sensor also includes a heater to keep the sensor free of moisture and condensation so as to improve accuracy and sensor longevity. 

Unlike some other brands, the Ecowitt LDS01 can be used with a variety of gateways and consoles, click here to view the latest Ecowitt sensor matrix.
