| Problem | Likely Cause | Solution | | :--- | :--- | :--- | | DO always HIGH (1) | Sensitivity too low | Turn potentiometer clockwise | | DO always LOW (0) | Short between probe traces or sensitivity too high | Clean probe with alcohol; turn potentiometer counter-clockwise | | AO reads 0 always | Broken wire or probe not connected | Check jumper between probe and control board | | Erratic readings | Power supply noise | Add a 100µF capacitor between VCC and GND | | No LED when powered | Reversed VCC/GND | Disconnect immediately; check wiring | Very low quiescent current, reported at approximately in

The applications of Hw-133-v1.0 can vary widely based on its design and capabilities. Some potential areas where such a component could be utilized include: Some potential areas where such a component could

The "v1.0" simply indicates the PCB revision. If you have this board, you have a device designed to detect water, moisture, or rainfall.

Once the multimeter shows your desired voltage (e.g., 5V), disconnect power, solder your device to the output, and you're ready to go. ⚠️ Essential Safety Tips Step-Down Only:
