This unfired bricks moisture detector circuit is composed of humidity detector probe, operation amplifiers N1-N8(IC1, IC2), LEDs(VL1-VL8)and resistors R1-R26, it is shown in the figure 8-75. After the power supply switch S is connected, the unfired bricks moisture detector circuit starts to work. When the humidity detector probe inserts the unfired bricks, it will produce a resistance value on the two sides of probe which changes with the water content of unfired bricks, this resistance value is amplified and processed by operation amplifiers N1-N8, the water content of unfired bricks is displayed by LEDs VL1-VL8 which is out-connected on the N1-N8 output terminal.
