Added Geiger Counter to my site

Nothing special or complicated http://www.lyndhurst-hill.info/weather.php look for the Radiation section.

Surprising how much background radiation I have.

Here is some explanation.

This is the unit I got.

Plug and play really, wrote a little php to upload to DB and I can retrieve the data from there.

They also have a google map, just like the rest of the world, interesting to see the Radiation numbers in Japan are lower than in my backyard…

Its something I have been trying to add, but what with the Japan incident getting hold of a detector is like finding hens teeth. Good job on the website with radiation info etc.

Hi H
The long awaited GM-10 arrived yesterday, got it up and running (testing here) http://www.newquayweather.com/wxradiationlocal.php

Couple of questions
Does your unit buzz ? I realise its probadly the high voltage. [ yes it does read the docs phil #-o]

I’m using the software that came with it, it says if you tick the ftp recording file on the recording tab it uploads the log file to with the graph, mine doesnt, it does every once and while, have emailed blackcatsystems, no reply as yet. Was hoping to extract data and get latest reading so stuck with graph for now.

Would you be willing to share your php code ?
Regards

Cool stuff, ya’ll have some great pages.

Curious, do you plan on putting up a comparison chart that compares your CPM to mSv ?? Your chart deals only with mSv, where your readings are in CPM (Counts Per Minute).

Also, did you get the USB or Serial Version?

Yes I in the processs of adding a comparision graph now getting a bit confused with mSv/hr, uSv/hr, mR/hr etc, and yes its the serial version, thought its easier to interface should I have a bash.

Its a sign of to much free time or the geek in me coming out Moventor

I’m interested in what assumptions you are making in that conversion too, since the vendor’s site implies that there is no direct conversion.

Hi I was using the info from this page http://www.blackcatsystems.com/GM/converting_CPM_mRhr.html but from this morning I am uploading to the blackcatsystems radiation map here http://www.blackcatsystems.com/RadMap/map.html so I have had to set the software to uR/hr for the map, this means my website now will display uR/hr rather than CPM and uSv for now.

Sorry or the delay Phil, yes always happy to share the code, nothing special. Ill attach it tonight.

I been changing the site to be more compliant with the templates from the “php wizards” on this forum. Makes it easier to “hand-over” when time comes.

Good stuff on the geiger.
Interesting to see how the readings go up and down when I walk past :-).

H.

Have you forgot to attach your memory is as good as mine, once I leave the room thats it #-o

LOL, together we might make up one. :-).

Here is the script.
http://www.lyndhurst-hill.info/Scripts/GM10.txt

Nothing special.

I use system scheduler to delete the file once I am done and I up load every min or so I think.

The script works on the principle that it counts the comma delimited fields, then adds some stuff such as month, day, year, hour, minute. I do this for all my data records. Simply because it makes it easier for me. I generally make graphs based upon month, day, year and hour. So all I have to do is avg(month) and it gives me the average for that month.

There are smarter ways of doing that, but when it comes to coding I like it easy (not much of a coder :-)).

There are 3 sections in the txt file.

• DB stuff, is the sql you can use to create a table that is supported by this script.
• PHP stuff, this is what you put in your php file to run to up date the db.
• Data example, this is how the data looks in the db.

Let me know how you go.

H.

Thanks for the script H, I will give it a go later today if I get some spare time and let you know.
