GrowCube moisture sensor calibration
Just installed a GrowCube and I have a sensor which is not reading correctly. The sensor appeared to be reading very low compared to the others. 28% compared to the 58% +/- on the others. Tried cleaning the contacts at the plug and got no improvement. Read a few postings here and saw there should be a moisture reading over 90% if emersed in water. Put all of the sensors in different containers with tap water and got readings of 95%, 95%, 65% and 95%, the 65% being the sensor which reads low in soil too.
It appears one sensor is faulty, however if there were a way to calibrate the sensor it might be useable still.
I suspect the only solution to my problem will be getting a replacement sensor, how would I do that if calibration is not possible?
