@ecabanas I am pretty sure you can compile OpenCV to run on the PI. I built a machine for my computer vision dev with a good video card so I could use the cuda cores build. Have you worked with any computer vision libraries? You will likely need a decent machine to do the processing. Maybe you could branch and build your own code base designed for the hardware you are considering. My experience is you have to do a lot of threshing of images, converting to gray scale, etc to do what you want. Your project is probably a little ambitious for a starter. You probably want to dl OpenCV and play around with the samples and take a look at some youtube videos for starters.

Hi Eduard, I know the topic is about 2 years old now. But since I am about to start a project and I plan to buy a decagon leaf wetness sensor I really wondered if you managed to get it running on the Arduino. Thank you very much Best regards Mathias

Hello, I hope your are still around about this topic. I very very oft read that we need to take twice the measure by inversing the polarity. As say the doc A special circuit is needed to measure the electrical resistance of the Watermark sensor. DC currents must not be allowed to flow through the wet part of the circuit, or else irreversible reactions will occur and spoil the readings. AC excitation avoids these problems, by reversing the polarity of the current many times per second, so that no net reaction takes place at either electrode In your above sketch, you do not inverse the polarity and it's look like you read 10 time with the same polarity. However, in the above schema, it look like you power (3.3 at the sensor) once the WATERMAK, and then 3.3 at the resistance. Could you explian me your sketch code? And what does the capacitor? Thank a lot..
