Automatic irrigation module DIY kit soil moisture detection automatic watering CD 4069 (Hex Inverter) The 2- or 4-quadrant multiplyingIntroduction: The fork shaped probe with two exposed conductors, acts as a variable resistor (just like a potentiometer) whose resistance varies according to the water content in the soil. This resistance is inversely proportional to the soil moisture: The more water in the soil means better conductivity and will result in a lower resistance. The less water in the soil means poor conductivity and will result in a higher resistance. The sensor produces
