MCP3008, NTC thermistor and RasPi

by RosscoS on Mon Mar 18, 2013 11:43 pm

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?

You don't necessarily need a connector, but the Pi Cobbler (http://www.adafruit.com/products/914) is a convenient way to connect a RasPi to a breadboard.

We have a tutorial that shows how to connect the MCP3008 to a RasPi here: http://learn.adafruit.com/reading-a-ana ... spberry-pi
When you void a product warranty, you give up your right to sue the manufacturer if something goes wrong and accept full responsibility for whatever happens next. And then you truly own the product.
