Good regards
I need some tips on how to construct a ultra cheap ph sensor My idea is to make abigger network of sensors to monitor the pH in a garden or a field Each sensor will be connected to a low-cost microcontroller like the CORTEX9 or MCS51 I saw the article.
Such an electrode is more robust than the traditional one
I do not know what material the electrodes are made, they sound like aluminum tubes and copper-bottomed lead with zink or silver polcart?? I also saw that in the past made them pH with alermony, but is poisonous and is not found anywhere There someone who knows me say what metal to use and if you have code before? .
"I need some tips on how to construct a ultra cheap ph sensor"
And what does that have to do with Keil products?
Did it occur to you to put those words into google?
"My idea is to make abigger network"
Bigger than what?
" to monitor the pH in a garden or a field"
Is it likely that the pH varies very much?
"low-cost microcontroller like the CORTEX9"
What is CORTEX9 ?
"I saw the article."
What article?
"Such an electrode is more robust than the traditional one"
Is it? How?
"I do not know what material the electrodes are made"
Time to get googling, then!
"they sound like aluminum tubes and copper-bottomed lead with zink or silver polcart?"
Do they?
"I also saw"
Where?
"that in the past made them pH with alermony"
What?

"alermony, but is poisonous and is not found anywhere"
Indeed. Alermony seems to be so rare that even Google can't find it!
antimony? Sb?
Can be quite poisonous to a relationship...
