I am not tied to any sensor, digital or analog. I have a few LM34's so I started working with them.
distance from the board will not exceed about 50 feet.
In looking it seems there might be A/D chips that would read the sensors then feed the data back via serial
or analog multiplexers that would allow me to send each of the A/I's a signal and change those inputs and let the on-board ADC do the work.
or, digital sensors.
my temperature span is about 0°F to about 110°F
I would be very happy to get 1/10th of a degree resolution.
as for calibration, I am hoping to put them all in a box and hope the temperature will stabilize and then move the box to the out side and let it stabilze as that freezing level.
thanks for the links.
suggestions are welcome !
