The Mini Humidifier Atomizer Module (Type B) is a compact, ready-to-use DIY humidifier kit designed for small-scale misting, humidification, and aromatherapy projects. It combines a 20mm ceramic ultrasonic oscillator with an integrated driver 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 oscillator that vibrates at 115kHz — a higher frequency than many standard atomizers — producing an exceptionally fine, consistent mist. The integrated driver 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 atomizer to the driver 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 2.5W power consumption is low enough for portable and battery-powered applications, while still producing a visible, consistent mist output suitable for personal spaces.
The Type B designation indicates the specific atomizer disc type and driver configuration, which is optimized for the 115kHz operating frequency and provides reliable, long-lasting performance. The ceramic oscillator 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, 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 oscillator and the integrated driver 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 oscillator 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 driver 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 Mini Humidifier Atomizer Module (Type B) provides a reliable, integrated solution. It is suitable for individual makers, students, and businesses purchasing in bulk for product development or educational programs.
