Working Principle: As seen in the figure 4-210,the soil moisture tester circuit consists of moisture detecting head, transistor V, diode VD1-VD4, LED VL1-VL5, potentiometer RP, power switch S and battery GB. When the soil is too dry, V and VD1-VD4 are disconnected. VL1-VL5 then are not illuminated. When the soil deteced are moist, the water in the soil will make the resistance value between the 2 elektrodes of the detecting head become small, so V is connected and VL1-VL5 are illuminated one by one. The moister the soil is, the stronger breakover ability V will have, so the illuminated LED will be more.   (View)
