SDMS40
Multipoint Scanning Snowfall Sensor

Now you can have a multipoint laser-based snow-depth sensor that is less complex and less costly than competing products. The SDMS scanning snowfall sensor has been proven trustworthy over years of field testing in harsh winter conditions. It quickly and reliably detects the onset of snowfall and snowmelt, as well as snow depth. It is compact and light, mounts easily, and filters out noise input for more-useful data. It is made more flexible by including both SDI-12 and RS-232 outputs. You can trust it for accuracy and reliability.
