5V USB 4-Head Ultrasonic Humidifier Mist Maker Module Type-C

The 5V USB 4-Head Ultrasonic Humidifier Mist Maker Module Type-C is a driver board (50mm x 30mm) powering up to four independent piezoelectric atomizer discs (20mm diameter with 12mm active ceramic area), operating from a standard 5V USB Type-C input compatible with USB chargers, power banks, laptops, or 5V adapters. The Ultrasonic Humidifier Mist Maker uses the same piezoelectric principle as piezo buzzers — but instead of producing audible sound, the ceramic disc vibrates at ultrasonic frequency against a thin water film, breaking the water’s surface tension into a fine cool mist without heating elements.

The mist maker humidifier driver board includes onboard push buttons with LED indicators for controlling each of the four atomizer outputs independently — useful for building multi-chamber diffusers, fog displays with multiple zones, or humidifier kits where different areas need separate mist control. Each atomizer connects via a PH2.0 interface cable (approximately 100mm length), and the included 100mm x 8mm ceramic filter rods draw water up to the atomizer disc through capillary action, keeping the disc surface wetted for continuous operation. The 5v mist maker module operating noise is described as ultra-silent ultrasonic operation — significantly quieter than fan-based humidifiers.

the 4 head ultrasonic humidifier module atomizer discs must remain wetted by water at all times during operation — running a piezo atomizer disc dry can damage the ceramic element, similar to running any ultrasonic transducer without its working medium. Available from StemVolt, this 5V USB Type-C 4-head ultrasonic humidifier mist maker module is ideal for engineers developing humidification systems, fog generation projects, and smart environmental control applications with efficient mist production.
