I have a KUS SSS Water level sensor for my RV that I would like to have trigger a NO 12v solenoid valve to turn off when my tank has reached full (and ideally also sound a little piezo). The sensor ranges from 240 Ω empty to 33 Ω full. I'd like to trigger at about 50 Ω. I'm wondering what would be the simple circuit to make this happen?

Fixed typos ("omh" -> Ω symbol, or could have used "ohms") to help non-native speakers etc. who might not recognise the typo.
