1wire programing

[philipgm]

I am looking for a small program that will read and store data from the 1-wire temperature sensor. This is a good way to add extra sensors for Cumulus users.
Maybe there is someone here who would like to give it a go.
Thank you
Philip

I have now written a program using java that reads the 1-wire temperature sensor and stores it in the xml file. The xml file can be sent to your website and used as extra data for your website. I will be testing this as a soil temp reading.
This program will be useful as extra sensors can easily be added to the website.
I will keep you updated.
Cheers

The program is at beta testing. I am using the program to read a soil temp sensor, and a sensor to read the sky temperature and compare that with the air temperature. The results then give a very good display of the amount of cloud at night. I will release the program in about a month.
At first I was using an xml file to send to the website for use but this has now changed to a onewiredata.txt file. A lot simpler to use.

The graphs are generated from JSON data using JavaScript, both in the user interface, and on the default supplied web site.

Why not going this way ? (along with .txt file)

That is way outside my programing skills!

Curious what 1wire hardware you are using and where you got the code from or did you write it yourself?

I have the book Weather Toys. In it has a lot of code you can use. Not sure if this is where he is getting the code from.

I took on the role of Guinea Pig for Phil who sent me up the hardware all ready to go.
The soil 1 wire sensor was easy and I just buried it.

The owl 1 wire sensor a little more work
Drivers and 1 wire software installed on PC.
Software reads in the temp data. Stores in small txt file. Cumulus uploads small txt file.
Using basic php and that txt file, parameters are set to give the calculated night sky. In my case I have Overcast, Mostly Cloudy, Partly Cloudy, Scattered Cloud, Mostly Clear and Clear.
You can put what you Like.
I have then prefixed that condition in front of my Current Conditions script.
http://wairoaweather.net/index.php?lang=en
During the day the Current Conditions displays my sky conditions from my solar.
At night when no solar value. I use the owl sensor. Hence this prefixed value can only be seen at night.
The Current Condition Script is here:
https://cumulus.hosiene.co.uk/viewtopic.php?f=14&t=12831
This 1 wire temp sensor can also be used during the day if one did not have solar. I think Phil uses the 1 wire during the day as well.

Initially the owl sensor sat out on the rail of my deck. But between house and trees, too much shade, too much shielding plus it was extremely hot and I was afraid it was going to melt as it has no housing just a lot of black gu
So a pole was purchased and of course as a woman would do, it was painted to match deck. Sensor now clears the house and trees and working as it should.
What I have found though, is parameters set by Phil in his php script were incorrect for my location. These had to be changed. Once moved to top of pole, where it is slightly cooler, again the parameters were incorrect and I had to change them again
So anyone interested you will have to watch your night sky and set accordingly.
Basically the 1 wire temp is compared with the Weather Station’s air temperature. The clear sky sucks heat out of the black covered 1 wire owl sensor. The difference gives you a pretty spot on display of the amount of cloud at night.
Unit-53 Phil has written his own code ( 2 small php scripts) I have used that and added to it.

OK, we have the program working. I am using it for soil temp and for estimating the cloud cover at night. It can also be used for establishing the daytime cloud cover. To access the program and instructions see:

Attached is a modified copy of the ‘Current Conditions’ Script - Version X.

Beteljuice has added in support for the 1 wire sensor as posted above by Phil.

There are two more choices listed under “User Variables’:
// *** NEW ***
$sensorCloudDAY = false; // Use 1wire cloud sensor DAYTIME (true/false)
$sensorCloudNIGHT = true; // Use 1wire cloud sensor NIGHTTIME (true/false)
Asd previously said, I am only using the 1 wire for the night Cloud cover hence ‘$sensorCloudNIGHT = true’ only.

NOTE: Although this version will work the same as the Original ‘Current Conditions’ Script
https://cumulus.hosiene.co.uk/viewtopic.php?f=14&t=12831

It is advisable to only use this version if you build Phil’s 1 wire Sensor for the cloud cover at night.

I just want to add a thanks to Phil here. This sensor is working pretty much spot on now for the cloud cover at night. I have stopped running in and out checking now, I trust my web site
