16mm Ultrasonic Humidifier Atomizer Disc Piezoelectric Mist Maker Transducer Module 108KHz
[Ultrasonic Sensor] The 16mm Ultrasonic Humidifier Atomization Module is a high-efficiency piezoelectric transducer designed for mist generation and humidification applications. It operates using ultrasonic vibration technology to convert water into ultra-fine mist particles quickly and efficiently. In addition, the module works on the principle of ultrasonic cavitation, where high-frequency sound waves generate rapid compression and rarefaction inside the water. As a result, microscopic water droplets are released into the air as cool mist. Because of its 108KHz resonant frequency, the atomizer produces fine and uniform fog particles while maintaining low noise operation. Furthermore, the compact 16mm design allows easy integration into humidifiers, aroma diffusers, medical atomizers, and DIY mist generation systems. The atomization disc is built using durable piezoelectric material for long operational life and stable performance. Moreover, the module consumes very little power while providing efficient mist output. ⚠️ Note: This atomizer module requires a compatible ultrasonic driver board for operation. The driver circuit is not included in the package and must be purchased separately. This ultrasonic humidifier module is widely used in humidifiers, beauty care devices, medical atomization equipment, aroma diffusers, and DIY electronics projects. 🔹 Key Features 16mm ultrasonic atomizer disc High-frequency 108KHz operation Fine and uniform mist generation Low noise operation Small fog particle output Long operational life High stability performance Low power consumption Suitable for humidifier and mist maker projects 🔹 Technical Specifications Product Type: Ultrasonic Atomizer Transducer Module Atomizer Diameter: 16mm Operating Voltage: DC 3.7V –5V Resonant Frequency: 108KHz Resonant Impedance: < 2 Ohms Coupling Factor: > 52% Electrostatic Capacity: 3000pF Spray Quantity: > 110mL/h Operation Type: Ultrasonic Piezoelectric Atomization Fog Particle Type: Ultra-Fine Mist Noise Level: Low Noise Operation Material: Piezoelectric Ceramic + Metal 🔹 Working Principle The ultrasonic atomizer uses a piezoelectric transducer immersed in water. When driven at high frequency, the transducer creates rapid mechanical oscillations that generate cavitation bubbles and surface waves. Consequently, microscopic water droplets are released into the air as cool mist with minimal energy consumption. 🔹 Applications This ultrasonic atomizer module is suitable for many applications, including: Humidifiers Mist makers Aroma diffusers Medical atomizers Facial beauty equipment DIY humidification projects Decorative fog systems 🔹 Package Includes 1 × 16mm Ultrasonic Humidifier Atomization Sensor Module
