Hi, I'm starting a beginner project for myself and I need a bit of suggestion from anyone who might have done this before.
I need to build a controller that reads the temperature of liquid in a tank and trigger a relay which will in turn activate a pump which will begin a cool down process. Currently this is controlled manually when a temperature alarm goes off I manually turn on the pump which cools down the tank. Ideal temperature is ~68F so I need the pump to turn on at 70F and turn off when the temp reaches 65F. The problem is this is an anodizing tank which contains sulfuric acid and distilled water (basically battery acid) so the environment for the sensor is pretty harsh. the sensor doesn't have to be TOO accurate it just needs to do it's job of keeping it around 68F.
does anyone have suggestions on what type of sensor to use?
As for a control module I was thinking arduino (because I have a few laying around) but I'm open to suggestions on that too. Thanks for being an awesome community! most of my answers have been answered by just doing some basic searches here but this time I've run dry on results.
