Ultrasonic Piezoelectric Humidifier Moisture Film Humidification 25mm

This Ultrasonic Humidifier Moisture Film Humidification atomization machine is suitable for high power, atomization plate tablet with a diameter of 25mm. This Ultrasonic Humidifier Moisture Film Humidification 25mm Piezoelectric Transmitter module works on the principle of cavitation produced by sound waves. As sound waves contain compression and rarefaction.

Due to extremely rapid movement, water droplets can no longer sustain their liquid state and gets converted into vapor immediately. This vibration is produced by a piezoelectric filament.

Note: This Module Needs Power Driver Board to drive, which is not included in a package. you have to buy it Separately.

The Ultrasonic Principle of Operation
A piezoelectric transducer immersed in a water bed, converts a high frequency, electronic signal into a high-frequency mechanical oscillation. As the oscillation speed is increased to a level where the water particles can no longer follow the oscillating surface, a momentary vacuum and strong compression occur, leading to the explosive formation of air bubbles (cavitation). At cavitation, broken capillary waves are generated, and tiny (1-micron diameter) droplets break the surface tension of the water and are quickly dissipated into the air, taking vapor form and absorbed into the air stream.
