Both our hardware and weather software were purchased from Ambient LLC.


They offered excellent pre and post sales support, as well as great prices.


The solution that we chose is very automated and requires little maintenance once installed and configured properly.

Our Weather Station Technical Specifications

Oregon Scientific WMR-112A Rain Gauge

The Rain Gauge measures rainfall in millimeter increments reflecting current rainfall or accumulation of up to nine (9) days’ history. The Rain Gauge features a self-emptying collection unit. The rainfall measurement range is 0" to 39.97" per hour with a cumulative operating range of 0" to 393.7". The rainfall accuracy resolution is 1 mm (0.04"). Data to the display unit is updated every 47 seconds. The Rain Gauge is powered by a solar cell with battery backup.

Note: March 23, 2015 - Partially due to physical damage, the rain guage had to once again be replaced.

Note: October, 2010 - After close to nine years of continual service out in the elements, our rain gauge failed and was replaced.

Rain Gauge
Resolution Modification

Our Rain Gauge - Resolution Enhanced

By design, the four inch opening of the gauge allows for a 1mm/hr (0.04in/hr).  Thanks to several people on the Ambient Support Forum for the great information and help in pulling off this project.

The goal of this modification is to increase the diameter of the collector opening thus increasing the number of "tips" of the internal measurement device.

The process is relatively simple and limited to two parts.

Phase 1 - Hardware Modification

  1. Purchase a large diameter funnel.  A funnel with a large opening with an inside diameter of exactly 8 inches would make the math (later step) easier but anything bigger than the original 4 inch opening is an improvement.  In my case, I found a 7.125 inch funnel.

  2. Cut off the tip of the funnel and any amount required to allow it to seat in the opening of the rain gauge.  A hack saw works well.  remove any rough edges resulting from the sawing.

  3. Closeup of ModificationAfter test fitting, draw a line around the outside of the funnel where it rests on the rain gauge.  run a bead of silicone caulk / adhesive on the bottom of this line, reseat onto the rain gauge, and smooth the caulk with a dampened finger.

Phase 2 - VWS Software Settings

  1. Since the modification increases the number of times that the buckets will tip in a given period of time, the calibration of the internal WMR-968 will be off.  Within the VWS software, this can be adjusted by changing the gain. This is accomplished under the menu "Settings", "Calibration", "Total Rain".

  2. To calculate the number to insert into this "gain" field, use the following formula:

    Gain = (d / D)2

    • d = internal diameter of the original rain gauge

    • D = internal diameter of the new opening (funnel)

    In my example above, the Gain was 0.3152 calculated by:

    Gain = (4" / 7.125")2

  3. After you enter and save this gain modification, your totals will be askew.  This is corrected by the menu "Settings", "Rainfall" and then correcting your monthly and annual totals.  Note: You may experience some error messages at this point.  Closing VWR and restarting it worked for me.

  4. At this point, go back into "Settings", "Rainfall" and verify that the settings are correct to date.  To get the annual total to display the correct total amount, you will likely need to enter an offset figure in the appropriate field  under the menu "Settings", "Calibration", "Total Rain".  Since the system resets the YTD total annually, you will need to remember to reset this offset to zero on January 1.
