1. Moisture Content Icons (1 to 3 drops indicate low, medium or high levels of moisture content) 2. Wood mode 3. Building Materials mode 4. Beeper mode 5. Moisture measurement 6. Display Hold mode 7. Battery status indicator Features • Pin and Pinless functions detect moisture in wood and building materials • Audible alert and Data Hold .We can see from the circuit schematic that the core of the module is a voltage comparator, which uses the common LM393. The positive phase input terminal of LM393 is connected to a voltage divider circuit composed of two resistors. The lower resistor is a soil moisture sensor. The soil moisture sensor is two electrodes. You can use this circuit to sense moisture content in various things and for that, the circuit will require a little modification. To modify it you have to experiment with different values of variable resistors in the place of 15K to change the sensitivity of the circuit according to the things in which moisture is to be sensed.
