Hi all,
I am researching a project to make a PID controller for espresso with a RasPi. As I will be controlling steam temps (~275F) as well as brew temps (~200F), this rules the DS18B20 out as its max temp is only rated to 257F.
So I was thinking of using a NTC thermistor and the MCP3008 with the RasPi.
In order to do this, do I need an interface board for the RasPi, or can I connect the MCP3008 directly to the RasPi?
