Two Modes: Press the switch once for continuous mode: the LED light stays on and the device sprays continuously. It will automatically shut down after 4 hours of operation for protection. Press the switch a second time to enter intermittent mode: the LED flashes, the device sprays for 10 seconds and stops for 5 seconds in a repeating cycle. It will automatically shut down after 12 hours of cumulative spraying for protection. Press the switch a third time to turn off the device.Installation: The white piezoelectric ceramic ring is the front and should be installed facing upward. The metal sheet is at the back and should be installed facing downward. Place the atomizer at the bottom of the water container; it must not be fully submerged. The red wire is positive and the black wire is negative.Principle: The piezoelectric ceramic drives the metal plate to oscillate at high frequency, creating ultrasonic vibrations that atomize the liquid. Micron-sized water particles are released through micro-pores to form a fine mist. The metal sheet features an oxidation-resistant silver coating for enhanced durability. Suitable for use in ultrasonic mist devices, USB humidifiers, aromatherapy diffusers, and similar applications.Features: Compact design with high atomization output. The solder joints on the switch can be bridged to enable constant power without switch control. Waterproof coating on the wire connections and a silver oxide layer on the atomizer provide added protection. The high-frequency oscillation system works with the circuit board to produce efficient atomization through a microporous aperture, generating a consistent fine mist.SPECIFICATIONS Humidifier Module Rated Voltage: DC 5V Rated Current: 300mA Frequency: 110KHz Power: 2W Power Type: Micro-USB socket Humidifier Interface: PH2.0 terminal PCB Size: 35x19mm, Weight: 4g Atomization Output: Approximately 40-50ml/h Microporous Atomizing Film Steel Sheet Diameter: 16mm Outer Diameter of Silicone Ring: 20mm Cable Length: 80mm Frequency: 110KHz Aperture: 4-5um Number of Holes: 740 Interface: PH2.0 terminal Material: Piezoelectric ceramic ring + Stainless steel Humidifier Cotton Swab Size: 100x10mm Black Bracket Size: 38x24mm, Weight: 4g Note: Printed markings on the PCB may vary by batch, but this does not affect functionality.How to Use: 1.
