Dear Folks,
I am trying to interface a PIC to a
Philips -> humidity sensor (capacitive varying).
From the datasheet it says
10% RH = 112pF
90% RH = 142pF
What kind of circuit could detect such samll changes???
The datasheet suggests this circuit BELOW
WHERE IS THE OUTPUT TO THE PIC??
Any easier circuits???
Thanx!
