Exploration of MAX1668
I received a few samples of the MAX1668 a few years back, for another project that is so far on the back burner, well… anyway.
The MAX1668 is a 5 channel centigrade temperature sensor. It sports one internal temperature probe and four external probes. The external probes are diode-connected transistors, opposed to thermisters or temperature to voltage converts like the lm35.
Since this project has the potential to get big, I’ve broken it down into “phases”
Starting with “phase one” … all I hoped to accomplish here is talking to the sensor via my microcontroller, and have it dump some basic data to the mcu’s seral port. *DONE*
Read Phase One
Now, onto “phase two” … what would a fancy indoor / outdoor thermometer be without a clock, and a user interface. Enter the DS1307 real time clock (separate write-up coming soon.)
Read Phase Two

Ok… I’ve been working on the project quite a bit, but getting bogged down with some nitty gritty things. I think I’ve moved into the beginnings of Phase Three. Goals for phase three; user interface, data-logging and statistical analysis.
