Electronic Spices 5V DIY Mist maker circuit board

This DC Ultrasonic Humidifiers Power Circuit Board with Atomizing Chip Moisture Film Humidification atomization machine consists of the atomization plate tablet with a diameter of 20mm. This Ultrasonic Humidifier Piezoelectric Transmitter module works on the principle of cavitation produced by sound waves. Just provide the DC3-12V power supply it will turn into a mini ultrasonic atomizer. As sound waves contain compression and rarefaction. Due to extremely rapid movement, water droplets can no longer sustain their liquid state and get converted into vapor immediately. This vibration is produced by a piezoelectric filament.
