The Complete 5V/2W USB Miniature Humidification Module Set (Type C) is a ready-to-use DIY humidifier kit designed for small-scale misting, humidification, and air quality projects. It combines a 20mm ceramic ultrasonic oscillating disc with an integrated drive circuit board on a single module, powered by a standard 5V USB supply. This makes it an ideal solution for custom humidifiers, desktop misters, aromatherapy diffusers, and DIY electronics projects requiring reliable ultrasonic atomization.
At the heart of the kit is a 20mm ceramic oscillating disc that vibrates at 115kHz — a higher frequency than many standard atomizers — producing an exceptionally fine, consistent mist. The integrated drive circuit board handles the high-frequency oscillation, eliminating the need for separate driver modules and complex wiring. The module is ready-to-use: simply connect the oscillating disc to the drive board, immerse it in water, and apply 5V USB power to begin misting.
The 5V USB power input makes the kit extremely convenient to use — it can be powered from any USB port, power bank, phone charger, or computer. The 2W power consumption is low enough for portable and battery-powered applications, while still producing a visible, consistent mist output suitable for personal spaces and small rooms.
The Type C designation indicates the specific oscillating disc type and drive circuit configuration, which is optimized for the 115kHz operating frequency and provides reliable, long-lasting performance. The ceramic oscillating disc is designed for continuous operation when properly immersed in water, with a typical lifespan of 3000–5000 hours.
The module is widely used in DIY humidifiers, aromatherapy diffusers, desktop misters, miniature fog machines, model-making effects, air quality projects, and educational science projects. It is also popular in commercial product development for small appliances and personal care devices.
The kit includes the 20mm ceramic oscillating disc and the integrated drive circuit board, with pre-attached wiring for easy connection. The compact form factor allows integration into small enclosures, bottles, and custom housings.
Important Note: The ceramic oscillating disc must be fully immersed in water during operation. Do not operate the atomizer dry, as this will cause overheating and permanent damage. Use clean water (preferably distilled) to prevent mineral buildup on the disc. The drive circuit board should be kept dry and away from water.
Whether you are building a custom humidifier, designing an aromatherapy diffuser, or adding misting effects to a project, the Complete 5V/2W USB Miniature Humidification Module Set (Type C) provides a reliable, integrated solution. It is suitable for individual makers, students, and businesses purchasing in bulk for product development or educational programs.
