Attach the atomizer to the circuit board. 2. USB DC 5V power supply. 3. Press the circuit board switch. 4. Atomizing plate suction water spray. NOTE: 1. Do not puncture the atomizer. 2. Can not run empty. 3. Do not use fast chargers. 4. No change circuit. 5. The circuit board must not be damp. 6. All steel sides absorb water downward. 7. Rated power input. Package Inlcuding: 4 X Atomization Module USB Interface 4 X Microporous Atomizing Film 4 X Humidifier Cotton Swab 4 X Black Plastic Bracket

• High-frequency oscillation, micrometer aperture, large atomization amount, fine mist particles, high spray rate, spray variety, timed shutdown. Note: The atomizing piece needs to be used together with the circuit board with the same frequency to achieve the ideal spray amount. Application: DIY spray, plant hydration humidification, landscaping atomization.
• Multiple spray modes can be switched at will. Meet different functional requirements. Two spray modes: press the switch for the first time is continuous spray mode: LED light is always on, always spray, spray 4 hours after the automatic shutdown protection. Press the switch for the second time is indirect spray mode: LED flashes, spray 10 seconds, stop spraying for 5 seconds, and so on, spray 12 hours after the automatic shutdown protection. Press the switch for the third time to turn off the machine.
• 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.
• How to use: 1. First install the atomizer plate, holder, cotton swab. 2. Connect the atomizer plate to the module port (White PH2.0 terminal). 3. Connect the power supply to the module power port (USB socket). 4. Press the power switch. 5. The atomizer plate will spray when it comes into contact with water.
