Bio Sample Tested & Results......

[dgs]

I'm sure it will have.

I am on with drying a batch presently with a humidity sensor with the little lcd display. The sensor is sat above the extraction fan on the turbo dryer. I am trying to see if there is a correlation between the readout and the bio water content as it dries.
With this same batch I am doing soap tests before and after centrifuging. I will report the results once completed.

... with a humidity sensor with the little lcd display. ...

So you've got the Arduino working then?

I wish I had julian.
It's one of these I have bought.

I'm sure this type won't work in bio but it is to see if it can detect when the air above the bio is dry (ish) so we can relate it to the water ppm in the bio. I've nearly finished the drying, 1 hour to go till it gets down to @ 50degs and it's reading 26% RH. At the 1/2 way mark the bio water was 210ppm.

My friend in the next village has been using this method for a couple of years, he brings his bio samples to me for testing (although he has a manometer) and strangely enough he has found that 26% RH on the sensor means his bio is dry enough.

Will post the full results tomorrow plus the soap tests.

Just realised it's not exactly like the ones in the link, it has temp plus RH.

I thought that when I looked at the link ... that's a very misleading advert, those are just thermometers.  But I think I know the type you mean.

So what's the latest on the Arduino?

You tell me which one.
I was reluctant to order another one from China after the empty package.

[Julian]

Try the cheap one.  What we're asking it to do isn't particularly taxing!

Let me know once it arrives.

[dgs]

Will Do, Thanks.

Sensor was like this one;

Ordered the arduino.

Bio Boy,

Just looked at your old post, it was the Cimtek Hydrosorb filter I meant in my posts where I said did you also pass your bio through that.

Hmmm, the spec is all about temperature and nothing about humidity ... wonder just accurate it is!

I think you'll be working on a whole new playing field once you get the Arduino board.

Bio Boy,

Nope. Passed via the spray bars and a 5 micron filter only. I gave up with the biotek filter when I was informed that it would be very limited in its ability to remove water despite its claims.
