Ultrasonic Mist Maker using 555 timer

Introduction

House of Hydro ultrasonic water foggers use high output ceramic discs, not the slow speed metal discs that collect buildup. The ceramic discs vibrate at an ultrasonic frequency to silently create microscopic (< 5 micron) water droplets. Ultrasonic humidifiers make a cool fog that is great for reptiles, greenhouses, and home humidification. Mist Makers use a piezoelectric transducer for a high frequency mechanical oscillation just below the surface of the water. This vibration creates a very fine, very dry fog that is instantly evaporated into the air. Water foggers do not use dry ice, fog liquid, heat, chemicals.

Working

  In ultrasonic mist maker/humidifier (also called an ultrasonic atomizer), a piezo atomizer disc/transducer (ceramic humidifier) works by transposing high-frequency sound waves into mechanical energy that is transferred into a liquid, creating standing waves. As the liquid exits the atomizing surface of the disc, it’s broken into a fine mist of uniform micron-sized droplets, so the key component required for this little project is a particular (20-mm, 113-kHz) ultrasonic atomizer disc/transducer (see below).
