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? .
Can be quite poisonous to a relationship...
