About This High-frequency oscillation, micrometer aperture, large atomization amount, fine mist particles, high spray rate. Note: 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 and stop. Pay attention to both sides of the atomizing sheet: 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. If the installation is reversed, it will not be able to spray. 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 hydration humidification, landscaping atomization. How to use: 1. First install the atomizer plate, holder, cotton swab. 2. Connect the atomizer plate to the module port (White 1.25mm terminal). 3. Connect the power supply to the module power port (Type-C socket). 4. Press the power switch. 5. The atomizer plate will spray when it comes into contact with water.
