Good evening,
You can give me more information and the configuration about the following product:
Added ability uses(wears out) has 1 wire snow detector (based one the leaf wetness now soil moisture 1 wire chip)
Thank you

there is work being done on producing a commercialy available 1 wire snow depth sensor, by Nafis
and I am adding support for it
(its based on the same routine as for the 1 wire soil moisture and leafg wetness sensors)
its a work in progress, and i will need to add routines to average the readings and put in temperature compensation
but for now you should get a voltage and temperature reading from the 1 wire sensor

Looks intersting Brian. I hope the have the ultrasonic one based on Stephan's up and running in a week or 2. That sensor is already temperature compensated so that should make things a little easier also. Thanks for helping out with this project.

Cheers

hi
your one is based on a 0 to 5v ADC
and so i will do a setup just for that type of sensor...and provide an average...and then some calibration...
have you been in contact with nafis about that different design?

Yes, I have been in contact with nafis and have all the parts to build the IR version. I've had the parts for a while just never got the time to get the project done and then the ultrasonic one looked easier. I'll be retiring in 10 1/2 months and hope to have a lot more time to tinker with the weather station then. Ha Ha  Thanks again.

Cheers

Mike,

I also prototyped an ultrasonic one based on the Parallax PING sensor (http://www.howmuchsnow.com/ping/).
The PING sensor is not temperature compensated like the SensComp one used in Steinar's prototype (http://voksenlia.net/met/snow.php), so I had to measure the temperature too.
So far the US sensor seems to drift around +/- 0.3"

Brian,

You should also take a look at the new CWOP Snow reporting form (http://www.madis-fsl.org/snow_data_login.html).
It's meant for manual snow data input, but we should be able write code to emulate the form entry. They have a place for snow depth. They only expect 1" accuracy for the snow depth. They also only expect the data once a day.

It's a shame they didn't add the input to the existing CWOP data stream...

I'd rather see data sent every 5 minutes so you can tell what's going on outside... but it's a start.

                                 Chris

yeah, not exactly very real time only once a day update
i do have a web post update componnent, but not really all that sure who to go about it
maybe some sort of script reading from a file on your website with the data in it?

Brian,

I working a snow detector that is based upon nafis' design i.e. IR based not ultrasonic.  How big of a hassel will it be to intergrate into WD? 

WD does find it and records data that is on the attached pic.

I turned it on today and that's as far as I've gotten.

Thanks,

Ed
