D20mm 113KHz Ultrasonic Humidifier Mist Maker USB Ceramic Atomizer Transducer Humidified Plate Accessories + PCB Module 5V

The D20mm 113KHz Ultrasonic Humidifier kit pairs a 20 mm ceramic atomizer transducer with a small 5 V driver PCB that is powered over USB. The driver vibrates the ceramic disc at about 113 kHz, which breaks water into a fine, cool mist. It is a simple way to build DIY humidifiers, aroma diffusers and mist effects for home, school and maker projects.
