The DIY Ultrasonic Mist Maker Kit is a complete, ready-to-assemble misting solution designed for humidifiers, foggers, and custom misting projects. It includes a PCB driver board, a ceramic atomizer disc, a mounting bracket, and a cotton wick — everything you need to build a functional ultrasonic mist maker. This all-in-one kit eliminates the need to source individual components separately, making it ideal for beginners, makers, and product developers.

At the heart of the kit is the ceramic ultrasonic atomizer disc, which vibrates at high frequency (typically 108kHz–115kHz or 1.7MHz–2.4MHz, depending on the variant) to break water into fine mist particles. The PCB driver board generates the high-frequency oscillation signal required to drive the atomizer, eliminating the need for separate modules and complex wiring. The kit is ready-to-use: simply assemble the components, immerse the atomizer in water, and apply power to begin misting.

The cotton wick is a key component in this kit. It draws water from the reservoir to the atomizer disc through capillary action, ensuring a consistent water supply for continuous misting. The wick also helps filter out larger particles, reducing mineral buildup on the disc and extending its lifespan.

The mounting bracket provides a stable platform for the atomizer disc and driver board, making it easy to install the kit in a water reservoir, bottle, or custom enclosure. The bracket keeps the atomizer at the correct depth in the water for optimal mist production.

The kit is powered by a standard DC supply (typically 5V USB or 12V DC, depending on the variant), making it compatible with USB adapters, power banks, and other common power sources. The low power consumption makes it suitable for portable and battery-powered applications.

The kit 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.

Important Note: The atomizer disc must be fully immersed in water during operation (or kept wet via the cotton wick). Do not operate the atomizer dry, as this will cause overheating and permanent damage. Use clean water (preferably distilled) to prevent mineral buildup. 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 DIY Ultrasonic Mist Maker Kit provides a complete, integrated solution. It is suitable for individual makers, students, and businesses purchasing in bulk for product development or educational programs.

Usage

Getting Started

  1. Assemble the kit — Mount the atomizer disc onto the bracket. Connect the atomizer leads to the PCB driver board. Insert the cotton wick through the bracket so it contacts the atomizer disc.

  2. Immerse the wick — Place the assembled unit into a water reservoir. Ensure the cotton wick is submerged and the atomizer disc is kept wet through capillary action.

  3. Connect power — Connect the PCB driver to a 5V USB or 12V DC power source (depending on the variant). The atomizer will begin producing mist immediately.

  4. Verify operation — You should see fine mist rising from the atomizer. If no mist is produced, check that the wick is drawing water and the wiring is secure.

  5. Adjust positioning — For best results, keep the atomizer disc horizontal and at a consistent depth in the water.

Important Safety Notes

  • Do not operate dry — The atomizer disc must be kept wet during operation (via immersion or cotton wick). Dry operation will cause overheating and permanent damage.

  • Use clean water — Distilled or filtered water is recommended to prevent mineral buildup on the atomizer disc.

  • Keep driver dry — The PCB driver board should be kept dry and away from water.

  • Ventilation — Ensure adequate ventilation around the driver board during operation.

Typical Applications

  • DIY humidifiers — Build custom desktop humidifiers

  • Aromatherapy diffusers — Add essential oils for aromatic misting

  • Desktop misters — Personal cooling and humidity control

  • Miniature fog machines — Small-scale theatrical effects

  • Model-making effects — Create fog and mist effects for dioramas

  • Educational science projects — Teaching ultrasonic atomization principles

  • Commercial product development — Prototype small appliances and personal care devices

Notes for Business Buyers

  • All-in-one kit — Reduces sourcing complexity and assembly time.

  • Cotton wick included — Ensures consistent water supply and extends atomizer life.

  • Standard power input — Compatible with widely available 5V USB or 12V DC sources.

  • Suitable for bulk purchasing — Ideal for humidifier manufacturers, diffuser brands, and educational institutions.
