The Ultrasonic Mist Maker is a device that utilizes ultrasonic waves to generate a fine mist of water droplets. This component operates by vibrating a ceramic disc at ultrasonic frequencies, causing water to break into tiny droplets and form a mist. It is widely used in applications such as humidifiers, decorative fountains, aroma diffusers, and theatrical effects. Additionally, it is a popular choice for DIY projects and environmental control systems.








The Ultrasonic Mist Maker is designed to operate efficiently with minimal power consumption. Below are its key technical details:
| Parameter | Value |
|---|---|
| Operating Voltage | 24V DC |
| Operating Current | 400-600 mA |
| Power Consumption | 10-15 W |
| Operating Frequency | 1.7 MHz |
| Water Level Requirement | Minimum 20 mm above the sensor |
| Mist Output | 300-400 mL/hour |
| Dimensions | Varies by model (e.g., 40mm disc) |
| Lifespan | ~5000 hours of continuous use |
The Ultrasonic Mist Maker typically has a simple interface with two wires for power input. Below is the pin configuration:
| Pin | Name | Description |
|---|---|---|
| 1 | VCC (+) | Positive power supply input (24V DC). |
| 2 | GND (-) | Ground connection for the power supply. |
Below is an example of how to control the Ultrasonic Mist Maker using an Arduino UNO and a relay module:
// Example: Controlling an Ultrasonic Mist Maker with Arduino UNO
// This code turns the Mist Maker ON for 5 seconds and OFF for 5 seconds in a loop.
const int relayPin = 7; // Pin connected to the relay module
void setup() {
pinMode(relayPin, OUTPUT); // Set the relay pin as an output
digitalWrite(relayPin, LOW); // Ensure the relay is initially OFF
}
void loop() {
digitalWrite(relayPin, HIGH); // Turn ON the Mist Maker
delay(5000); // Keep it ON for 5 seconds
digitalWrite(relayPin, LOW); // Turn OFF the Mist Maker
delay(5000); // Keep it OFF for 5 seconds
}
| Issue | Possible Cause | Solution |
|---|---|---|
| Mist Maker not producing mist | Insufficient water level | Ensure water level is at least 20 mm above disc. |
| Device overheating | Running without water | Always operate with sufficient water. |
| Weak or no mist output | Dirty or worn-out ceramic disc | Clean or replace the ceramic disc. |
| Intermittent operation | Unstable power supply | Use a regulated 24V DC power supply. |
| Mist Maker not turning ON via Arduino | Incorrect relay wiring or code issue | Check wiring and verify Arduino code. |
