I have to measure two temperatures:
the first one outdoor,
the second one indoor.
I was thinking to use two common
sensors: AD590 for the outdoor
and LM335 for the indoor.
Temperatures must be displayed
in °C so I have to make
a conversion via software.
I was thinking to do as follows:
For the outdoor:
Input0 (as RSE), a 10k resistor
between AI0 and GND (so to make
conversion 10mV/°K)
For the indoor:
Input1 (as RSE), a 4~5k resistor
between AI1 and +5V pin;
LM335 between Input1 and GND
What do you think about?
Is it ok or it's too minimal?
Is there any alternatives do
you suggest to adopt instead?
Thanks in advance
