The Okdo TelePort soil moisture sensor which can measure the soil moisture. When it is inserted in the soil and the current passes though the soil, the sensor will read the current changes and convert the resistance value into the water content. The higher the resistance value, the higher the soil conductivity. Additionally, the metal on the surface can extend its life expectancy. Compatible with RJ11 6P6C OKdo TelePort Control boards and expansion shields
Two conductive tines are inserted in to the soil providing an analog representation of the moisturecontentwithin the soil
