Make a Soil Moisture Meter With the Help of Arduino

I am an academician in Faculty of Agriculture. We have a lot of experiments in field and measure some parameters that are constraint to do. One of the compulsory measurement is determining of soil moisture. Estimation of soil moisture as using soil sampler is more accurate measurement, but need to so much labor and time. So I decided to make a soil moisture meter with the aid of arduino and soil moisture sensor. I hope it will be useful for you.”
