PFULTR Dual Spray Ultrasonic Atomizer Module

Take your DIY humidifier, misting fountain, or home fragrance projects to the next level with this compact Dual Spray Ultrasonic Atomizer Module by PFULTR. Powered via a universal Type-C connector at DC 5V, this auto-spray module activates the moment it contacts water — no buttons, no complicated setup. Its microporous ceramic atomization sheet vibrates at 108–110 KHz to produce an ultra-fine, uniform mist perfect for desktop humidifiers, hydroponic systems, aroma diffusers, and creative DIY builds.

Key Features

Efficient Dual-Spray Atomization: Microporous atomization sheet with a resonant frequency of 108–110 KHz delivers fine, even mist output consistently.
Low Power Consumption: Operates at just 3–3.5 W, making it energy-efficient for long-term, continuous use.
Auto-On Design (No Switch): Simply supply power and introduce water — the module starts misting automatically. No manual switch required.
Compact & Lightweight: At just 36 × 21 mm, this module slots easily into tight enclosures, custom builds, or DIY project housings.
Universal Type-C Power Input: Convenient DC 5V supply via standard Type-C port; compatible with most USB power adapters (standard chargers only — fast chargers not compatible).
Alloy & Ceramic Construction: Durable materials ensure a long service life for the atomization sheet and bracket assembly.

How to Set Up

Attach the atomizer bracket and cotton swab assembly.
Connect the atomizing plate to the module's atomizing plate port.
Plug your power supply into the module's power port via the Type-C connector.
Switch on your power source.
Place the cotton swab in contact with water — the module begins misting automatically.

Important Safety Notes

Do not puncture the atomizing plate or bend/pull the welding points.
Do not power on the module without connecting the atomizing plate first.
Do not use fast chargers — standard 5V USB adapters only.
Do not modify the module in any way.
Keep the control module itself dry at all times — only the cotton swab should contact water.
Install with the steel sheet (raised surface) facing downward so the cotton swab can absorb water correctly.
Always operate within the rated power input.

Frequently Asked Questions

Q: What can I use the Dual Spray Ultrasonic Atomizer Module for?

A: This module is ideal for a wide range of DIY projects, including desktop humidifiers, aroma mist diffusers, hydroponic growing systems, fogger displays, decorative water features, and custom electronic builds. Its compact 36 × 21 mm footprint and Type-C DC 5V input make it easy to integrate into almost any project enclosure.

Q: Does this atomizer require a switch to operate?

A: No — this module features a no-switch, auto-spray design. Once the power is connected and the cotton swab contacts water, atomization begins automatically. Simply connect your 5V Type-C power supply and introduce water to start the misting process instantly.

Q: What power supply should I use with this module?

A: Use a standard DC 5V USB power adapter connected via the Type-C port. Fast chargers are strictly not compatible and must be avoided to prevent damage to the module. A rated current of 600 mA at 5V is sufficient for reliable, continuous operation.

Q: How do I prevent water from damaging the control module?

A: Only the cotton swab component should contact water. The control module itself must be kept completely dry at all times. Install the unit with the steel plate's raised surface facing downward so the cotton swab draws water up through capillary action, protecting the electronics above.
