pt1000 maxim
I need to write a program to drive 4 solar heat collectors. The idea is to regulate switchable ( 4 positions ) water pump witch pumps water true 2 x 2 paralleled collectors to collect much heat energy as possibly.
Im not sure about last part ... I guess high enough temperature is target.
Since client do not know much about MCUs and control, im been told to do a switching thing related to temperature signal (like a comparator based switching).
My plan is to use pic 16f887, It got 14 ADCs and many many pins.
Since i do not have much experience and iv much time ... im asking for advise
Previously iv programmed pic 16f84 to blink leds and it seemed not complicated at all.
After all can i handle project so "big" and how good the´program quality should be , coz this thing need to drive almost whole system without any failure ?
Some smaller questions.
-Is the Pt 1000 best choice and can i connect it like a potentiometer.
- Will pic16f887 handle this job, coz there will be 10 + sensors, Large 4 x 20 char lcd and some more ? It takes 1 ADC pin per sensor right ?
- Something important, i should know ?
Thank you !
