Soil Moisture Sensor (Resistive)

John Phillips

This sensor is an INPUT device. It measures the moisture in a ground medium such as soil. It is an analogue device. The principles of Electrolysis and Electroplating can also be demonstrated by observing that the metal coating of one of the prongs deteriorates over time. Specification Power supply: 3.3v or 5v Output voltage signal: 0~4.2v Current: 35mA Size: 60x20x5mm …
