The worldwide supply of raspberry pi's available through ordinary retail channels is zero right now (or was the last I looked). But they'd be a good choice.
Russell, Huh! Part of the computer chip shortage?
The missing information is "how far away is your coffee roaster?" If you are close enough, you could use a microcontroller like an arduino or similar and interface with the sensor of your choice directly to a PC over USB. Your range with USB is usually 5 meters.
I want a small unit (an arduino would be fine) that sits next to the roaster and stores data on an SD card, USB drive, or similar storage device.
I don't know very much about measuring temperatures up to 500F, I am mostly interested in air temps and related phenomena. Look on some place like adafruit.com for a sensor and how to interface with it.
There seem to be availble probes but finding a sensor to which the probe connects that works with an arduino or raspberry pi has been a challenge. The adafruit.com web site has a probe/sensor with a maximum temperature of 125F and I didn't see a 'contact us' link where I could ask about a higher temperature sensor. Thanks, Rich
