RE: RE: RE: RE: Virtual Rain Sensor

Still not going to cut it. On site collection of rain data is the only sure fire solution. Furthermore, your "local" weather station will typically not have the data required to run the Penman-Monteith equation, and even if it did, this data is also better collected on site.
You are missing the point. The whole idea is to leverage a nearby personal weather station (average of a $1000 investment) so that everyone doesn't need to make that investment. Most of the stations we have found have all the data we need (some don't have solar radiation so we look to the next nearest). All of them have relative humidity, temperature (and dew point), altimeter, anemometer, and elevation (the rainfall isn't actually used in the P-M equation but we use it to figure out how much we still need to water).

Agreed

Hey,
Definatly purchase the Hunter Mini-Click or bettwe yyet for another 20 dollars you can buy a Hunter Wireless Rain Click (no wire hookup). thats a definate...but the Hunter Computer program is nothing worth while...all it is...is that the Pro-C appears on yuour computer and you can make program changes from your computer, instead of walking to the controller....dont worry about the Computer Programming,,,but definatly the rainsensor....i would buy the HUnter Wireless Rain Click from Sprinkler Warehouse.
I agree.

RE: RE: RE: Virtual Rain Sensor

What I am defining as a "virtual rain sensor" is basically using the closest weather station (personal or otherwise) as my rain gauge. More accurately I am using a Penman-Monteith equation adjusted by region using Department of Agriculture data. I have also extended the algorithm to adjust for forecast precipitation.

You can now download the application and try it out. Early adopters will have lifetime gratis accounts by helping work out the bugs.

RE: RE: Virtual Rain Sensor

"Virtual rain sensors" simply will not cut it. Also, I sincerely hope you are not using CIMIS data and trying to apply it to other regions.

RE: Virtual Rain Sensor

Definatly..........let me know which rainsensor you went with?[8D]
I chose to NOT go with a rain sensor. Instead I made a program which pulls the weather observations and runs the CIMIS calculations on transpiration and evaporation to figure out how much rain we need. It then deducts any rain we actually received and converts the solution to a runtime for the valve to be on through inexpensive X10 parts. Let me know if you are interested in trying this service free of charge (beta program) at reskin@virtualrainsensor.com
