The adobe moisture detector circuit is composed of the humidity detection probe, op-amps N1 ~ N8 (IC1, IC2), light-emitting diodes VL1 ~ VL8 and resistors R1 ~ R26, and it is shown as the chart. R1 ~ R26 choose l / 4 W carbon film resistors or metal film resistors. C select the CD11 series of aluminum electrolytic capacitor with voltage in 16V. VL1 ~ VL3 and VL6 ~ VL8 select φ3mm red high-brightness light-emitting diodes; VL4 and VL5 use φ3mm green high-brightness light-emitting diodes. IC1 and IC2 select LM324 Quad op-amp circuit. CB chooses the 6 ~ 9V laminated battery.
