Jrifedptry 6Pack DC 5V USB Humidifieration Atomization Disc Mirco Interface Atomization Drive Circuit Board for DIY Home

The white piezoelectric ceramic ring is the front , which is installed upward, All steel sheet is the suction on the back, installed downwards. The red wire is positive and the black wire is negative. 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 , plant humidification, landscaping atomization. Two modes: the switch for the first time is continuous mode: LED light is always on, always , 4 hours after the automatic shutdown protection. the switch for the second time is indirect mode: LED flashes, 10 seconds, stop spraying for 5 seconds, and so on, 12 hours after the automatic shutdown protection. the switch for the third time to turn off the machine. High-frequency oscillation, micrometer aperture, large atomization amount, fine mist particles, high rate, variety, timed shutdown. The atomizing piece needs to be used together with the circuit board with the same frequency to achieve the perfectspray amount.
