Hello friends, I hope you all are doing great. Today, I am going to share the new Capacitive Soil Moisture Sensor Library for Proteus V1.0 . The capacitive soil moisture sensor v1.2 is the long black board you push into the soil of a pot or a garden bed to know when your plants need water. It is the sensor behind automatic watering systems, smart plant pots, greenhouse monitors and garden data loggers. Unlike the older two-fork resistive sensors, its copper never touches the soil, so it does not corrode, and it is the soil sensor most Arduino makers buy today. Behind the part sits our own model , written from the published data. It gives the voltage a real board gives for the soil around it: the water in the soil sets its permittivity (the Topp equation from soil science), and the permitti ...
