Snow Science

Take a look at the SDI-12 portion of our manual here: https://sensorlogicinc.github.io/snodar-releases/sdi12_info/

Our sensor is not compatible with the Kestrel network, so the SNOdar will be independent of the Kestrel. If you have a battery or line power at the Kestrel site, you should be able to tap into power there. 

USER GUIDE - this is our Github for the SNOdar product.

We have also released Chairlift. The Chairlift Gateway will send your data to a cloud where you can grab it and merge it with your Kestrel data or display it on your website.

We advertise the range of 9 centimeters to 9 meters. Outside of that range, you should still have success, but our testing indicated this range is something we can stand behind with complete confidence. 
For more information similar to this, along with specifications, features, applications, etc. you can reference our SNOdar page HERE.

The daylight savings time is strictly for the app/user settings and the 24-hr snowfall reset, is geared more toward ski resorts. The actual data is time-stamped with Unix.

Upon booting up the sensor, you may find the sensor health is poor, e.g. a notification will show up on the sensor saying Sensor Init Failed.

First, re-boot the sensor and restart the mobile app. If there are still error messages after repeating this, contact SensorLogic with the failure code(s) so we can help troubleshoot a solution.

Radar Modules

Our SLMX4 radar modules don't work in a native bistatic radar configuration.  Each module has a Tx/Rx antenna pair, in a monostatic fashion.  However, they could be networked over WiFi and be set up monostatically around an area, to provide a pseudo-bistatic setup.

Furthermore, multiple X4 chips can be synced to provide a MIMO virtual array.  We are currently testing prototypes to leverage this capability.

The only way to set up a true bistatic scenario is to separate the antennas with a long RF cable via our old Onza development kits, as the SLMX4 currently does not support connectorized antennas.

If you are interested in running the Health Firmware, please follow the firmware update guide so you have the correct firmware on the unit.  By default, they come with the MATLAB development firmware.

Once you have the correct firmware, the windows laptop should automatically recognize the device but if not follow the USB driver installation help.

Last, start the app and connect, using the windows app guide.  There is also a python wrapper and demo for the Health firmware.

Radar Detection And Ranging

Radar was initially developed in the early 1900’s as a technique to measure distance, direction, and speed of objects by transmitting pulses of high-frequency electromagnetic waves. These electromagnetic waves reflect off the object and back to its source. The time it takes the electromagnetic wave to return to its source is translated into a distance to the object.
