A capacitive moisture sensor works by measuring capacitance changes caused by the changes in the dielectric. It does not measure soil moisture directly (as pure water does not conduct electricity well), instead it measures the ions that are dissolved in the moisture. Capacitive sensors are used as a manual button replacement.
Capacitive sensing is divided into two types: active and passive. Active sensing involves an electronic component such as a sensor or amplifier to detect small changes in capacitance. On the other hand, passive sensing relies on some simple circuitry and no additional electronics. How does it work?
