Driven by a matching ultrasonic driver circuit (sold separately), it is the core component of DIY humidifiers, aroma diffusers, foggers, and mist-based cooling systems. The 20mm disc size is the most common standard for consumer humidifier replacement and DIY mist maker projects.\u003c\/p\u003e\u003ch3\u003eKey Specifications\u003c\/h3\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eParameter\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eDiameter\u003c\/td\u003e\n\u003ctd\u003e20mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Frequency\u003c\/td\u003e\n\u003ctd\u003e2.4MHz (ultrasonic)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003ePiezoelectric ceramic transducer\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMist Output\u003c\/td\u003e\n\u003ctd\u003e~300–500mL\/h (with matching driver)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Voltage\u003c\/td\u003e\n\u003ctd\u003e24V AC (via driver circuit)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMist Temperature\u003c\/td\u003e\n\u003ctd\u003eCool mist (no heating)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch3\u003eHow It Works\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eThe piezoelectric disc vibrates at 2.4MHz when driven by an ultrasonic driver circuit\u003c\/li\u003e\n\u003cli\u003eVibrations create cavitation at the water surface, atomizing water into 1–5μm droplets\u003c\/li\u003e\n\u003cli\u003eDroplets form a visible cool mist without heating the water\u003c\/li\u003e\n\u003cli\u003eRequires a 2.4MHz ultrasonic driver module (not included) for operation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eWhy Choose This Transducer?\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e✅ \u003cstrong\u003e20mm standard size\u003c\/strong\u003e — direct replacement for most consumer humidifiers\u003c\/li\u003e\n\u003cli\u003e✅ \u003cstrong\u003eCool mist\u003c\/strong\u003e — no heating element, safe for essential oils and aromatherapy\u003c\/li\u003e\n\u003cli\u003e✅ \u003cstrong\u003eHigh mist output\u003c\/strong\u003e — ~300–500mL\/h with matching driver\u003c\/li\u003e\n\u003cli\u003e✅ \u003cstrong\u003eDIY friendly\u003c\/strong\u003e — easy to integrate into custom humidifier and fogger builds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eTypical Applications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eDIY ultrasonic humidifier build\u003c\/li\u003e\n\u003cli\u003eAroma diffuser and essential oil fogger\u003c\/li\u003e\n\u003cli\u003eStage fog and mist effect machine\u003c\/li\u003e\n\u003cli\u003eGreenhouse and terrarium humidification\u003c\/li\u003e\n\u003cli\u003eArduino-controlled mist system\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003ePackage Contents\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e1 × 20mm 2.4MHz Ultrasonic Piezoelectric Mist Maker Transducer\u003c\/li\u003e\u003c\/ul\u003e\u003cp\u003e\u003cem\u003eUltrasonic driver circuit not included.\u003c\/em\u003e\u003c\/p\u003e","brand":"Keszoox","offers":[{"title":"Default Title","offer_id":46991449358571,"sku":"\u003cnone\u003e","price":5.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0677\/1005\/8731\/files\/20mm-2-4mhz-ultrasonic-mist-maker-piezoelectric-transducer-humidifier.webp?v=1761802316","url":"https:\/\/keszoox.com\/products\/20mm-2-4mhz-ultrasonic-mist-maker-piezoelectric-atomizing-transducer-humidifier","provider":"Keszoox","version":"1.0","type":"link"}
