Capacitive soil moisture sensor

Description

Soil moisture sensor with analogue output that performs capacitive measurement. It consists in measuring the capacitance with a capacitor probe generating an alternating electric field. The probe has a pointed tip, which allows it to be easily inserted into the ground. The analog output voltage level increases in proportion to the ground moisture level. The sensor has a built-in voltage stabilizer and is supplied with a voltage ranging from 3.3 V to 5.5 V. It can be used, for example, in automatic watering systems.
