@b--yeezi That looks like exactly the sort of submersible temperature sensor that should work! It's exactly the same core component as far as the RaspberryPi is concerned, they've just stuck it to a heat-conducting piece of stainless steel and sealed it up so that it can be submerged into whatever liquid (or potentially-wet weather, etc) you might want to monitor. From what I read, you'll need a 4.7kOhm resistor between two of those leads (the "module" I'm using[1] has that built onto the board already) but otherwise you should be able to plug it right in and use it exactly as described.

@ClaudioM thanks for the encouraging feedback! I swear I really am trying to produce _much_ more often than I have been. Probably more short episodes coming Real Soon Now!...
