The adobe moisture detector circuit is composed of the detection input circuit and LED display circuit, and it is shown as the chart. The detection input circuit consists of the testing probe, operational amplifier integrated circuit IC1 (N1, N2), resistors R1 ~ R8 and water content measurement area selection switch S1. LED display circuit consists of the LED linear analog display driver integrated circuit IC2, LEDS VL1 ~ VL10 and point / line selector switch S2. R1 ~ R8 select the 1/4W carbon film resistors or metal film resistors. C select the aluminum electrolytic capacitor with voltage in 16V.
