[time-nuts] [Solved] Looking for multiple PPS timestamp logging

[Mark Sims]

Use an LM34 sensor,  not the LM35.  It has twice the resolution per volt since it outputs in degrees F,  not degrees C.

Better yet,  use the DS1620 (old revision) that is used on the Tbolt.  It has a digital interface.  It will give you around 0.01C res without any ADC conversion noise, etc.


-------------------
You'll need to cobble up a sensor, of course, and I don't know if the resolution of the di145 is good enough (20mV/LSB as I recall) for a LM335 (10mV/Kelvin?).
