EC probe recommendations
I'm blown away by what MyCodo can do! I've been looking for some time for a platform to make hydroponics monitoring and dosing easier and never found anything close to this. Thanks Kyle Gabriel for the incredible work!
I bought the AnyLeaf pH probe and a couple of generic peristaltic pumps but I'm struggling to find an EC probe. I had a look through the MyCodo supported input devices page and it seems that only the Atlas Scientific EC probe and Xiaomi Miflora are supported EC probes.
The Atlas Scientific EC probe is a great deal pricier than the AnyLeaf pH probe and shipping to where I live (Australia) is $70! I asked the AnyLeaf guys their recommendations and they said they're researching EC probe development but haven't got anything going yet. All I can find on the Miflora probe is a little palm-sized, battery-powered, multi-probe. I need something quite robust that can stand continuous immersion. It seems custom inputs are supported if I write my own module in Python.
Does anyone have any EC probes they recommend and have working will MyCodo?
Any suggestions would be greatly appreciated!
I haven't experimented much with EC myself. Water sensors are difficult to make and get right. Atlas Scientific makes quality products and although pricier, are worth the money, especially for sensitive measurements such as EC. If you happen to come across any other good EC sensors and want help creating an Input module, let me know and I'll see if I can help.
Thanks Kyle, I'll continue the hunt and let you know if I find anything decent. Otherwise I'll just go with the Atlas Scientific. Thanks for the advice!
Hello everybody. I live in Russia and Atlas Scientific does not ship to our country. I ordered everything except the EC, CO2 and PH sensors on aliexpress.
Look please. These sensors will work.
THANKS IN ADVANCE
I had a brief look at the DFRobot pH and EC sensors, but they seem to be a bit iffy with longevity under continuous immersion. I bought the Anyleaf instead for pH and that seems to be working a treat. I haven't found a decent alternative to the Atlas EC probe yet that's rated for continuous immersion. Also you'll need a temperature sensor to go along with that DFRobot EC probe if you want accurate measurements. Not sure about the CO2. Hopefully someone with more knowledge can help you more than I!
All the best.
hello @in03 Thank you very much for your reply. Yes you are right. These Sensors do not last long. We'll have to order through intermediaries.
What was the expected lifetime they had stated?
I bought DFRobot EC and PH probes as the site I went through said they were capable of prolonged immersion.😪
Bit of a battle getting the right numbers for the EC probe (haven't calibrated the PH one yet)
It seems a bit vague but in the specifications section there's a bullet point stating:
"- Probe life > 0.5 year (depending on frequency of use)"
Not sure what to do with that, but coupled with a warning against continuous immersion I wouldn't be game to use it in a production system. Would be interesting to test it and see how long it lasts though?
Atlas rates their EC probes for 10 years before recalibration/replacement with continuous immersion.
