I am in the process of designing an electric brew system and since I am a newbie, I need some help with Temperature sensors.
I am trying to understand how this whole aspect of electric brewery works.
What types of temperature sensors are there?
I keep seeing thermowells used to protect sensors from getting exposed to liquid. Is that really necessary?
What about the end point connection for sensor? It seems to be either 2 or 3 wires or these funky M8 connectors.
I am thinking of developing my Own PID with something like this
My goal is to have as much customization as possible.
