4Pcs Single Spray DC 5V Humidifieration Atomization Disc Type-C Interface Atomization Drive Circuit Board No Switch No Timing Function

The atomizing piece needs to be used together with the circuit board with the same frequency to achieve the ideal spray amount. | Continuous spray mode: Spray immediately after power on (No Switch). Input DC5V power supply, LED light is always on, always spray. Shutdown: Unplug the power input. | 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. The red wire is positive and the black wire is negative. | Spray Principle: Piezoelectric ceramics drive metal plate high-frequency oscillation, ultrasonic liquid atomization. Micrometer-fine water molecules atomize water throughmicropores and disperse it into the air. Application: DIY spray, plant humidification, landscaping atomization. | High-frequency oscillation, micrometer aperture, large atomization amount, fine mist particles, high spray rate.
