This thread is to document the build of a Digital Brew Thermometer.
Abstract:
I want a digital thermometer which can stand up to the demands of brewing.
Features:
1) Stainless steel construction
2) Battery powered and self contained.
3) Should be able to output 5 Volt control signals to turn on/off Solid State Relays
4) Alarm output
Current Design.
Mechanical:
1/4 Stainless Steel Cap. (McMaster Carr)
1/4 24 inch stainless steel pipe threaded both ends
Sensor
1) Analog Devices TMP03 MEMS based sensor (150 degree C max temp)
Processor+ display
ATXMEGAA3BU-XPLD evaluation board (Mouser has these).
We will provide all of the code open source for non-profit use.
Please suggest features. I figure we need to be able to
1) set some target temps and dwell times,
2) 10 steps....
3) Identify the Action when a target temp is reached (Turn on output 1, set alarm etc...)
I have the parts coming in, and I have built two of the sensors, I will post pictures...
What do you think?
