Ultrasonic fog generator, which allows you to turn water into fog.It is made on a 2SC2562 transistor and a 2.4MHz piezoelectric element
I bought the piezoelectric element on Aliexpress, its price is about 2 US dollars.Diameter 20 mm
Here are the characteristics of the transistor 2sc2562.Other transistors with similar characteristics can also be used, it will only be necessary to select a capacitor C2 according to the maximum generation power.
The piezoelectric element on the contact side must be isolated from water, otherwise water will get on the contacts and electrolysis will begin
With a power supply of 30 Volts, the current consumption will be 600 mA.The transistor will heat up and it must be installed on the heat sink
The piezoelectric element will have a signal in the form of a sine wave with an amplitude of about 25 volts
