## Overview

The EC Buying 3Pcs USB Humidifier Module is a compact, 5V atomization circuit board designed for DIY and experimental use. Featuring a 110KHz high-frequency oscillation and a micrometer-level 5μm aperture, it delivers a large volume of fine mist with a high spray rate. Its durable design includes waterproof adhesive and a silver oxide protective layer, ensuring reliable, oxidation-resistant operation. Ideal for incubation and humidification projects, it offers easy power-on functionality and precise frequency matching for optimal atomization.

## Description

Product parameters PCB board size: 35mm*19mm/1.38*0.75inch Voltage: 5V Current: 300mA Frequency: 110KHz Power: 2W Aperture: 5um Holes: 740  Wire length: 80mm/3.15inch Atomized steel sheet diameter: 16mm/0.63inch Rubber ring diameter: 20mm/0.79inch Rubber ring thickness: 4mm/0.16inch Atomizer material: shockproof silicone ring, piezoelectric ceramic ring, stainless steel sheet  Pay attention to the front and back sides during installation The white piezoelectric ceramic ring surface is the front spray surface, which is installed upward All steel sheet surface is the suction surface on the back, installed downwards

## Features

- High-frequency oscillation, micrometer aperture, large atomization amount, fine mist particles, high spray rate
- The atomizing piece needs to be used together with the circuit board with the same frequency to achieve the ideal spray amount
- The left and right welding points of the switch can be welded together to realize power on, i.e. spray, without the need to control the switch
- There are two wires, the red wire is positive and the black wire is negative. The wire is 80mm long and there are terminal blocks at the end of the wire
- There is waterproof adhesive on the welding points of the wires to prevent circuit breakers, and a silver oxide layer on the surface of the atomizing sheet to protect the coating from oxidation
