4-Way Ultrasonic Mist Maker / Humidifier DIY Kit
This 5V Type-C 4-Way Ultrasonic Mist Maker DIY Kit is a high-volume, multi-channel micro-atomization system engineered to transform water into a thick, cool fog instantly. Powered by a modern, high-efficiency driver board, this versatile circuit can coordinate up to four piezoelectric ultrasonic transducer discs simultaneously or in custom patterns. Complete with four matching highly absorbent cotton fiber wicks, it serves as the ultimate core module for custom desktop humidifiers, aromatherapy oil diffusers, incubator humidity setups, and theatrical scenic fog decoration installations.
Unlike traditional thermal humidifiers that boil water and consume large amounts of electrical energy, this system utilizes high-frequency mechanical vibration. The micro-perforated transducer plates vibrate at ultra-high frequencies, breaking the surface tension of water to push out micro-fine water droplets without generating any heat. The board is fully pre-assembled with plug-and-play white terminal headers, making it completely accessible for students, maker hobbyists, and product prototyping engineers.
## Technical Specifications* Product Classification: Multi-Channel Ultrasonic Atomization Driver Circuit Board
* Operating Input Power: DC 5V (Standard USB power rail)
* Power Supply Port: Reversible USB Type-C Female Interface
* Resonant Oscillation Frequency: ~108kHz to 110kHz (Micro-pore piezo standard)
* Output Channel Array: 4 x Isolated 2-Pin Male Terminal Headers
* Control Interfaces: Onboard physical micro-tactile push-buttons for pattern cycling
* Mist Particle Volume: Ultra-fine microscopic mist output per active channel
* Wicking System: 4 x High-density capillary action cotton fiber wicks included## Key Product Features
* Massive Quad-Spray Output Capacity: Outfitted with four independent drive circuits, this module can power four individual humidifier discs at once, flooding your room or project enclosure with a vast volume of soothing, cool mist in seconds.
* Universal Type-C Connectivity: Ditching obsolete micro-USB connections, this driver board features a modern USB Type-C input port. It runs smoothly on standard 5V mobile phone chargers, portable power banks, vehicle USB ports, or desktop computer terminal bays.
* Onboard Dynamic Mode Switches: Features twin tactile click-buttons right on the printed circuit board. These let you change modes on the fly—switch from running all four nozzles constantly, to alternating between channels, or firing specific sides to perfectly tailor how fast you add moisture to the air.
* Precision Micro-Pore Metal Plates: Each transducer disc is engineered with thousands of laser-drilled micro-apertures in its central steel grid. This configuration guarantees consistent droplet size, prevents large water sputtering, and reduces mineral clogging over prolonged operation.
* Complete DIY Implementation Bundle: Ships with four custom-sized absorbent cotton sticks that draw water steadily to the underside of the atomizing discs through capillary action, ensuring a steady water feed without flooding the top face of the electronics.## Ideal Application Areas
* Smart Home Upgrades: Foundation for crafting custom, high-output desktop mist humidifiers or automatic smart aroma diffusers.
* Agricultural & Biotech Systems: Automated humidity control inside small greenhouse tents, hydroponic propagation chambers, or bird/reptile egg incubators.
* Artistic Installations: Creating cool fog layouts for model landscapes, table fountains, tabletop volcanoes, and stage craft scenery.——————————
## Critical Setup and Orientation Guidelines
To avoid user setup errors, component damage, and low customer feedback ratings, place these technical tips on your storefront listing:* Transducer Disc Face Orientation: The piezoelectric discs have a front side and a back side. The front side (which usually features a slightly convex center or a small white ring perimeter) must face upward toward the air. The reverse flat metallic side must press firmly against the wet cotton wick. If flipped upside down, the disc will pool water on itself and fail to produce mist.
* First-Time Wick Saturation: Before powering on the module for the first time, submerge the cotton wicks completely in pure water for 2 to 3 minutes until they are thoroughly soaked through to the core. Attempting to run the driver board while the wicks are bone dry will cause thermal stress on the transducer discs, leading to permanent circuit failure.
* Liquid Medium Restrictions: This kit is designed to work with clean tap water, distilled water, or water mixed with a few drops of water-soluble essential oils. Do not use heavy, thick, or oil-based perfumes, as they will coat the micro-pores, block the vibration mechanism, and permanently ruin the discs.——————————
If you’d like to tailor this product description further for your active store layout, let me know:* The exact dimensions of the green circuit board or the cotton wicks in millimeters to add to the specifications datasheet
* If you want to format this as a punchy summary optimized for short mobile shopping apps like Shopee or AliExpressI can modify the layout text to suit your exact storefront needs.
