USB 5V Ultrasonic Humidifier Driver Board Kit

DIY USB Ultrasonic Humidifier Kit for Fine, Consistent Mist

Build your own compact ultrasonic humidifier with this USB-powered driver board and atomizer plate set. Designed for makers, repair technicians, and product developers, this kit provides the core electronics needed to drive a mini mist module for desktop, in-car, or small-space humidification projects.

The kit includes a 5V ultrasonic mist maker driver board and a 16 mm round atomizer plate with silicone ring. Operating at an ultrasonic frequency of approximately 110 kHz, the atomizer plate produces an ultra-fine mist (around 5 μm droplet size) through 740 densely distributed spray apertures. The atomizing sheet surface is treated with an oxidation-resistant silver layer to help protect the coating and support longer service life. The driver board delivers a stable waveform with low driving voltage, low power consumption and low impedance, helping to maintain consistent atomization performance.

The driver board is powered via a 5V DC source (typically from a USB supply), with a working current of about 300 mA and power consumption around 2 W. Board size is approximately 46 × 20 × 17 mm, making it suitable for integration into small enclosures, custom housings or replacement applications. The atomizer plate has a steel sheet diameter of about 16 mm and an outer silicone ring diameter of about 20 mm, with an approximate wire length of 8 cm for flexible positioning inside your device design.

Why It's a Smart Choice

• Compact, low-power 5V design integrates easily into USB-powered humidifiers and small DIY projects.
• High-density atomizer plate and stable driver waveform support fine, uniform mist output for more even humidity distribution.
• Oxidation-resistant silver coating and environmentally friendly electronic components contribute to reliable, long-term operation.

FAQ

Q: What is included in the kit?
A: The package contains 1 humidifier driver board and 1 round 16 mm atomizer plate with silicone ring.

Q: What power supply do I need?
A: Use a regulated 5V DC supply (commonly from a USB port or USB power adapter) capable of providing at least 300 mA.

Q: Can this be used to repair an existing mini humidifier?
A: Yes, if the original device used a similar 5V ultrasonic driver and 16 mm atomizer plate, this kit can often be used as a replacement, provided size, wiring and electrical specifications match.

Q: Is this a complete humidifier?
A: No. This is a core electronic kit (driver board + atomizer plate). You will need your own housing, water container, power supply and any control circuitry or switches.

Q: Does it support continuous operation?
A: The module is designed for typical mini humidifier use. For extended continuous operation, ensure adequate heat dissipation, correct water level management and follow your project's safety and testing requirements.
