If you're going to be installing anything in adverse environments or for any period of time PLCs are the go-to for a lot of one-off solutions. Some of them get pretty spendy quickly but Automation Direct has some reasonable($100-200) PLCs[1]. I ended up automating our entire greenhouse with one including a PID based water pump to drive a bunch of different downstream outputs that worked really well.

- johnwalkr 3y agoThere’s a lot of hardware projects that are arduinos, raspberry pi, and spark fun sensors when they should be PLCs and industrial sensors just because people have never been exposed to PLCs.
- Already__Taken 3y agoit's not just exposure but writing PLC is like going back to 1991, no source control, no tests, no deployment because you're writing in production. it's easier to bring cheap hardware up to par than it is to replace a vendor software.
