It’s commonly built with a positive and negative plate, with a dielectric medium separating it in the middle. The capacitive soil moisture is set as the input using the pinMode() function. A capacitive moisture sensor works by measuring the changes in capacitance caused by the changes in the dielectric. These are freewheeling diodes, used against back EMF protection. Most capacitors contain at least two electrical conductors often in the form of metallic plates or surfaces separated by a dielectric medium. The available water capacity (AWC) is the range between these It does not measure moisture directly (pure water does not conduct electricity well), instead it measures the ions that are dissolved in the moisture These ions and their concentration can be affected by a number of factors, for example adding fertilizer for instance will decrease the resistance of the soil.
