2. Sicherheitshinweise

Soldering involves high temperatures and can produce fumes. Always adhere to the following safety precautions:

• Arbeiten Sie in einem gut belüfteten Bereich, um das Einatmen von Lötrauch zu vermeiden.
• Tragen Sie eine geeignete Schutzbrille, um sich vor Spritzern oder umherfliegenden Teilen zu schützen.
• Verwenden Sie einen Lötkolbenständer, um versehentliche Verbrennungen zu vermeiden.
• Ensure the soldering iron is unplugged and cooled down when not in use.
• Elektronische Bauteile vorsichtig behandeln, um Schäden durch statische Elektrizität zu vermeiden.
• Halten Sie einen Feuerlöscher oder eine Löschdecke in der Nähe bereit.

4. Montageanleitung (Aufbau)

Follow these steps carefully to assemble your humidifier kit. Refer to the 'Step By Step Instruction' section within Image 2 for visual guidance on component placement and soldering.

1. Bereiten Sie die Leiterplatte vor: Identify all component locations on the PCB.
2. Solder Surface Mount Components (SOT-23 MOSFET): This is the smallest component. It is recommended to solder one pad first, align the component with tweezers, then solder the remaining pads. The kit includes extra MOSFETs in case of error.
3. Lötwiderstände: Match resistor values to their designated spots on the PCB. Resistors are not polarized.
4. Solder Diodes: Pay attention to the polarity (band on the diode matches the marking on the PCB).
5. Lötkondensatoren: Electrolytic capacitors (larger, cylindrical) are polarized; ensure the longer lead (positive) matches the '+' marking on the PCB. Ceramic capacitors (smaller, disc-shaped) are not polarized.
6. Solder LED: The longer lead of the LED is positive and should match the '+' marking on the PCB.
7. Solder 2-pin Sockets: Solder the small 2-pin headers into their designated spots.
8. Solder Temperature & Humidity Sensor (DHT11): Bend the pins as needed and solder the sensor into place.
9. Drucktaster löten: Solder the four small push buttons and the larger power button into their respective positions.
10. Solder Micro USB Port: Carefully solder the Micro USB port to the PCB.
11. Assemble Humidifier Module: Insert the piezoelectric element into its black plastic housing. The larger of the two openings on the housing should face upwards. Route the piezo wires through the square hole where the two halves meet.
12. Mount OLED Display: Solder the OLED display module to its designated header pins on the PCB.
13. Gehäuse montieren: Use the provided screws and standoffs to secure the PCB between the acrylic plates. Ensure the humidifier module is correctly positioned with the cotton stick extending downwards.

• Time Left: Remaining time on the timer.

Erste Verwendung:

1. Insert the humidifier into a glass or container filled with water, ensuring the cotton stick is fully submerged and the electronic components are above the water level.
2. Connect the USB power cable to the device and a 5V DC power source.
3. Press the yellow POWER ON/OFF button to turn on the device. The display will illuminate.
4. Use the MENU button to navigate to settings. Use UP/DOWN buttons to adjust the target humidity or timer. Press OK to confirm.
5. Press the START/STOP button to begin humidification. Mist should start to appear.

6. Wartung

To ensure optimal performance and longevity of your MUXWELL DIY Humidifier, follow these maintenance guidelines:

• Wasserqualität: Use clean, distilled, or filtered water to prevent mineral buildup on the humidifier module.
• Cotton Stick Replacement: Replace the cotton stick regularly (e.g., every 1-3 months, depending on usage and water quality) to maintain mist output.
• Reinigung: Periodically clean the humidifier module and its housing to remove any residue. Use a soft cloth and avoid harsh chemicals. Ensure the device is powered off and disconnected from power before cleaning.
• Lagerung: When not in use for extended periods, ensure the device is clean and dry. Store it in a cool, dry place.

7. Fehlerbehebung

Sollten Sie Probleme mit Ihrem Luftbefeuchter haben, beachten Sie bitte die folgenden häufigen Probleme und Lösungen:

• Kein Nebelausstoß:
  • Ensure the cotton stick is fully saturated with water.
  • Check if the humidifier module (piezoelectric element) is correctly installed and connected.
  • Verify the device is powered on and the START/STOP button has been pressed.
  • Ensure the water level in the container is sufficient and the cotton stick is submerged.
• Incorrect Humidity/Temperature Readings:
  • Check the connection of the DHT11 sensor to the PCB.
  • Ensure the sensor is not obstructed or exposed to extreme conditions.
• Gerät lässt sich nicht einschalten:
  • Verify the USB power cable is securely connected to both the device and a working 5V power source.
  • Check the soldering of the Micro USB port and power button.
• Schaltflächen reagieren nicht:
  • Inspect the soldering connections for the unresponsive buttons.
