## Description

Atomization module with 4 channels and 20mm piezo discs, generates fine mist for humidifying plants, fountains or DIY projects, simple power supply via USB-C at 5V, offers simultaneous, dynamic or incremental spray modes, uses microporous foil for efficient nebulization and extended coverage.
The atomization module consists of an electronic board and 4 20mm piezo discs that, in contact with water, nebulize the liquid, being ideal for applications ranging from plant humidification to creative DIY projects such as generating mist in a fountain or ambient humidifier.
It benefits from several spray modes such as single, dynamic or multiple spray.
It uses microporous foil atomization technology, creating a fine mist with extended coverage. Water is drawn from under the disc and is pushed and nebulized to the top of the disc. Requires a sponge to pick up the water and spray it.
Power is supplied directly with a USB Type-C cable and a USB charger capable of 5VDC.

Use:
Attach the atomizing heads to the appropriate connectors.
Connect the module to a 5V USB power source with a Type-C cable.
Make sure the module is positioned on a stable surface, away from excessive moisture.
Select the desired spray mode depending on the application.
To start, press the SW1 button, in normal mode, all spray heads work simultaneously.
For dynamic spray mode, press SW2 button. In this mode, spray heads 1, 2, 3 and 4 are activated successively, at one second intervals, then deactivated in the same order, from left to right. After head 4 is turned off, the cycle resumes automatically.
When the SW2 button is pressed for the second time, only the first spray head will be activated, and with each subsequent press, one more head will be added to the function, until all are activated.
The module automatically turns off after 2 hours.
DO NOT USE WITHOUT WATER! Using the piezo disc dry will cause it to crack and stop working!
