Hello AAC forum members,
My electronic skills are cro-magnon in comparison to most, so I do apoligize if my questions seem a little blind.
I am currently trying to adapt a soil moisture probe to science application:
http://www.vegetronix.com/Products/VG400/
Which also comes with a relay board:

The moisture that I am using on this sensor does not have a medium though (no soil), it is being sprayed with atomised mist.
I have connected this probe to a multimeter, but when the probe receives a shot of mist, the voltage only raises between 20-40mV.
With a medium and water saturation, the range would usually indicate between 3V (saturated) and 0V (completely dry)
Based on the parameters of the probe and relay board, how can I amplify this to give me a larger reading?
explanations/diagrams/cheap circuit to buy welcome
Thankyou in advance.
