The Atomizer_5V_module is an ultrasonic atomization module that utilizes high-frequency vibrations to break down liquids into ultra-fine particles. It is designed for ease of use, featuring onboard status indicators and dual-control modes.
The module includes two high-brightness LEDs:
- Red LED: Indicates power status.
- Blue LED: Indicates active atomization work.
Equipped with an integrated frequency-adaptive circuit, the module supports microporous atomization plates within the 100kHz to 160kHz range (optimized for 108kHz or 150kHz center frequencies). It automatically detects and adjusts to the required driving frequency of the plate. With its PH2.0 anti-reverse interfaces and Lego-compatible mounting holes, it is ideal for DIY projects and industrial prototypes.
| Parameter | Value |
|---|---|
| Operating Voltage | 4.0V - 5.0V |
| Operating Current | 120mA |
| Vibration Frequency | 108kHz (Adaptive range: 100kHz - 160kHz) |
| Control Interface | 3-Pin PH2.0 (GND, VCC, Signal) |
| Peripheral Interfaces | 2-Pin PH2.0 (Atomizing Plate & Battery Input) |
| Operating Temp | 0°C to +70°C |
| Communication | Direct I/O Control (Active Low) |
| Dimensions | 22.4mm x 38.4mm |
| Atomizer plate size | Diameter 20mm |
| Mounting | Lego compatible & M4 screw holes |
| Pin Name | Description |
|---|---|
| G | GND (Ground) |
| V | VCC (Power Input 4-5V) |
| S | Atomization Start Control (Active LOW) |
| WH | Atomizing Plate Interface |
| + | Battery Positive Terminal |
| - | Battery Negative Terminal |
- Manual Control: Use the onboard DIP/Slide switch to manually trigger the atomization.
- MCU Control: Connect the S (Signal) pin to a microcontroller I/O.
- Pull the pin LOW to start atomizing.
- Pull the pin HIGH to stop.
- Connect the microporous atomizing plate to the WH interface.
- Ensure the plate is in contact with water (usually via a cotton wick).
- Apply 5V power to the VCC/GND pins.
- The Red LED will light up.
- Trigger the S pin or toggle the switch; the Blue LED will light up as mist is generated.
The following code demonstrates how to control the atomizer module using an Arduino. It will turn the mist on for 5 seconds and off for 5 seconds.

Atomizer_5V_module Control Example
The 'S' pin is Active Low.
*/
const int atomizerPin = 3; // Connect 'S' pin to Digital Pin 3
void setup() {
pinMode(atomizerPin, OUTPUT);
digitalWrite(atomizerPin, HIGH); // Start with Atomizer OFF
}
void loop() {
// Turn ON Atomization
digitalWrite(atomizerPin, LOW);
delay(5000); // wait for 5 seconds
// Turn OFF Atomization
digitalWrite(atomizerPin, HIGH);
delay(5000); // Wait for 5 seconds
