I installed our second Ambient personal weather station two months ago. It replaced an Ambient "FALCON" PWS that we had for about two years. (That one failed due to my ineptitude.)
Based on my experience I can share some comments.
Our 2902C has a smallish console and the display seems to have been chosen for a small farm. I will try to include a picture of ours to illustrate this.
The console is in our kitchen and the sensor array is 100+ feet away so the signal has to go through several walls, interior and exterior, to register on the console.
Included on the display is: UVI and LIGHT in the lower right corner and RAIN in the lower left corner.
It's the UVI and LIGHT that make me think this one has features for a farm. I seldom pay attention to them.
The RAIN display can tell the total rain record since (I guess) the last time the PWS was started (so it resets when? This I do not know). Also the total of the last rain EVENT, I guess that means the last rain-fall recorded, and the weekly total. Again that suggests to me a farm environment.
I really think this 2902C records low as we are about 3 miles from a small airport that has a Government Weather reporting station and it reports more rain and higher wind gusts - different enough for me to notice.
Two more comments - installing both PWS sensor arrays was a pain in the neck. The North arrow is cast into the upper surface of the plastic body as if you could look down on it while you are trying to align the array to north-facing. As it seems to be generally recommended that the Array be isolated from local buildings, trees and obstructions that seems like a bad design to me. Your experience may vary, of course.
Finally I found the instructions for the first PWS to be just awful. It was a cut & paste document and that showed. The instructions for the 2902C are better but still have at least one curious shortcoming - calibration of the barometric pressure. At one point is stated you can calibrate the pressure, at another is stated you cannot. Confusing.
Finally I never succeeded in getting either station to broadcast data through our home router to any of the websites that except PWS data. Again your results may vary.
