This Ultrasonic Humidifier Moisture Film Humidification atomization machine is suitable for atomization plate tablet with a diameter of 20mm. This Ultrasonic Humidifier Piezoelectric Transmitter module works on the principle of cavitation produced by sound waves. Just provide the DC3-12V power supply it will turn into to a mini ultrasonic atomizer.
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 vapour immediately. This vibration is produced by a piezoelectric filament.
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 vapour form and absorbed into the air stream.
Note: This Module Needs USB to 3.5mm male jack Power cable to drive, which is not included in a package. you have to buy it Separately.
