The DC 5V 108KHz Ultrasonic Humidifier Mist Maker USB Spray Module is a high-performance piezoelectric transducer system engineered to vaporize liquid molecules without raising their temperature. Operating at a standard DC 5V input voltage, the driver board utilizes high-frequency oscillator logic to generate an exact 108KHz electrical resonant signal. This high-frequency signal is transferred to a precision-engineered atomization transducer disk coated with an anti-oxidation, acid-resistant glaze layer.

The atomizer disk features thousands of laser-drilled micropores across its center. When the 108KHz drive waveform passes through the piezoelectric crystal, it causes rapid mechanical vibrations. These vibrations pull liquid upwards through surface tension and force it through the microscopic holes, breaking it down into a smooth, ultra-fine cold mist cloud. Because the driver incorporates an onboard hardware tactical push-switch, users can easily toggle between continuous dispersion modes and intermittent duty-cycle pulsing.

Key Features and Benefits

• Micro-Fine Cold Mist Production: Utilizes high-frequency 108KHz vibrations to break water into a gentle fog without using heat, keeping the environment safe and preventing accidental burns.

• Universal Micro-USB Power Interface: Plugs directly into standard 5V mobile phone chargers, power banks, computer ports, or standalone development board power rails.

• Dual-Mode Operational Logic: Integrated tactical button cycles between continuous spray mode, 3-second intermittent pulse mode, and a soft standby power-down state.

• Corrosion-Resistant Glaze Protection: The transducer ring features a specialized chemical coating that protects the vibrating crystal face against hard water scaling and essential oil residue.

• Energy-Efficient, Safe Drive Circuit: Consumes very little power (up to 2 Watts maximum), making it perfect for portable, battery-powered IoT devices and desk accessories.

Technical Specifications

How to Use

1. Connect the Transducer: Plug the pre-soldered 2-pin JST wire from the microporous atomizer disk into the output terminal header on the 108KHz driver board.

2. Prepare the Water Wick: Position a cotton filter swab or sponge wick inside a clean water reservoir so that it is fully saturated. The bottom surface of the atomizer plate must sit directly against the wet cotton pad to draw water up efficiently.

3. Orient the Transducer Disk: Ensure the disk is facing the correct direction. The front side (often flat or marked with a small ridge) must point upward toward the air, while the reverse side rests against the wet wick.

4. Supply Input Power: Plug a standard Micro-USB cable into the board and connect it to a 5V power source. The onboard status LED will light up to confirm the board has power.

5. Select the Mode: Press the tactical switch once to turn on Continuous Spray Mode. Press it a second time to switch to Intermittent Pulse Mode (3 seconds on, 3 seconds off). Press it a third time to turn the module off.

Applications

• DIY Smart Home Humidifiers: Connects easily to Arduino or ESP32 relay shields to build automated, humidity-controlled home systems.
