Hi there I need some advise needed for my University research project.

What I am intending to do is to measure the humidity levels 
in a crop canopy over a 8-24 hour period. The simplest way to 
do this (I thought) would be simply to connect up some type of
device (variable resistor ??) that is sensitive to changes in 
humidity to an analogue data logger which the university 
already have (maybe in working order). The restrictions that 
apply are that there is no AC power supply available in the 
field and that my electronics knowledge is very limited.

I have spoken to several local electronics firms about trying
to find such a 'device' but without any great success (Hopefully
this is due to their lack of interest in the small quantities 
concerned). Does anybody know of the existence of a device that 
would suit these purposes ???


Thanks in advance

Peter.
