In the spare time I don't have I have been thinking about whether I could hook up a raspberry pi to record pH and temperature. Temperature seems relatively trivial and I presume as accurate as most thermometers but pH seems a little bit more involved.
The bits to connect the probe to and handle input looks ok but I am struggling with probes....
I came across https://www.amazon.co.uk/dp/B00MGDWZ9I but it seems considerably cheaper than others I have seen so makes me think it would be useless?
I know probes are meant to be kept in a solution when not in use but would leaving it in the tank be ok? Does this type of probe have consumables that need replacing or could this just work forever?
