## Description

Ultrasonic atomizer kit powered by 5V via MicroUSB, ideal for humidification and misting projects in small containers. Includes 20mm piezoelectric disc and sponge stick for constant water supply. Offers dispersion of up to 35 ml/h, low consumption of 2W and silent operation under 36 dB.
Mist maker kit with ultrasound and MicroUSB power that can be used as a humidifier.
The kit includes:
- The module
- Piezoelectric disk
- Sponge bar
Instructions:
The disc generates fog when in contact with water by oscillating at a certain frequency that allows this. The kit includes a stick made of absorbent material used to transfer the liquid to the disc.
The disc is placed directly on the end of the sponge, which in turn must be in permanent contact with the water. It will take the water and take it to the base of the disc to be atomized.
Using the kit without liquid will damage the piezoelectric element!
