Hi,
I am trying to design a simple system that measure the humidity in my car and switches on a small fan when it reaches a threshold, powered by say a 9v battery, not by the car battery.
So I am trying to research humidity sensors and really can't find out too much about the implementation and operation.
One such is http://www.spiratronics.com/data/8315.pdf but the data sheet doesn't give any info other than electrical characteristics.
Can anyone point me in the right direction please?
