Hi! I got here via link from hackaday.io, many interresting blog posts here but links I have tried lands on a 404-not-found page.

I did find the right links by going to your member About page and then My content.

I'm a user and trying to find someone to put the system together. However, I'm starting with 40-20mA analog sensor to avoid noise. Interfaced with a current-to-voltage converter, then output is the input to 1024 positions digipot, included for calibration, then to 16 bit ADC and to esp32.

With the code above, will we not need the digipot?

Nice project. Now I'm really curious if the polarization could be minimized with taking two measurements per cycle, but flipping the HIGH and LOW in between, so it would be kind of square wave ac.

Hello all

has anybody managed to make this with arduino nano? Do you know the internal resistance of the digital pins?

Hi! congratulations for your work! 'm also experimenting with arduino from some years trying to monitor and automate climate, irrigation, etc ... I would be happy to show you if you were interested ... but unfortunately my knowledge of programming, but above all of electronics, is often not enough.

I am having difficulty rewriting the sketches to calibrate and monitor EC-PPM ("three dollars EC PPM meters") for Wemos D1 mini (ESP8266) (although you have already answered questions in the comments somewhere ... I did not understand how to integrate the piece of code you posted).

bye

RE: Automated Green House Blog:11.1 - Self Optimising Automated Nutrient Doser - EC Optimisation

I have built this project and I can't find the sketch download with libraries zipped as described. I realize this project is older, but I'm entering a contest and have designed and built my system around this project, so I really need to find those libraries. I have found lots of dead links in the search, but I would really appreciate help. I have the code from Blog 11.1 but I can't get the Read Me file because I don't have the Download Zip, and I'm pretty sure I'm going to need the libraries. I do have the hardware built and I'm just waiting on the software so I can load it and try it out.

Thank you for this incredible design and software, and thank you for your time in reading this and hopefully your assistance.

SUPER!

I have used a resistor for now anyway, but if I don't have to solder an extra part in, I definately won't be upset either.

So it's most appreciated that you posted the link. Thanks a lot.

Hi Michael,

I discovered your EC-Meter El Cheapo a while back and I tried it and it worked just fine, except that I used a different temp sensor which wasn't doing too well (extreme fluctuations in temperature, which led to fluctuations in the EC reading accordingly...) But nevertheless, you did some really fantastic work there and it'smost appriciated from my side. Thanks a lot.

In the meantime I organized the recommended DS18B20 sensor, but I can't find your download file with the specialised onewire & dallas files anywhere. Could you be so kind and send me a download link or the files?

Regards

I liked it, but just couldn't see where the electronics would go.

Can u please provide me the schematic. i am also pursuing a project on ph meter.

Hi R. Scott,

I went back and looked at your previous posts which I had over looked before. Biology is not my focus interest but what you have done is very interesting. This also points out how important it is for one to not get too specialized. Applications of electronics to other sciences abound but are only able to be realized if someone like you is sufficiently diversified and can recognize them. Great Job.

John

How long do these phases take? (When do we see the next blog?) [View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-e3e57d73-3b2e-4de8-b4b2-0cac91220603/contentimage_5F00_1.png:16:16]

Amazing what you can learn on this forum....

How sensitive are these spores to light?

I though most fungi preferred low light?

bmyrand — Mon, 08 Oct 2018 06:15:32 GMT

is this project still active ?

wish i could download that .zip file somewhere for the libraries.

i would like to add 2 dozing pumps to that to add ph up or ph down as required.
