- 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.
