Have you ever bought a humidifier? Have you seen it work—bringing out mist? In truth, the process is called water atomizer.
Also, a water atomizer combines air and water to generate fine mist. Indeed, it creates this mist by breaking down droplets of liquid.
Perhaps the bigger question here is: How does a water atomizer work?
This article will show you how a water automizer works and how to use it with Arduino to create different projects.
So, let’s get started.
How does a Water Atomizer Work?
In truth, a water atomizer is the first choice when you need humidification, odor control, or dust suppression. But how does this device work?
Well, as we mentioned earlier, the water atomizer uses the principle of airflow and suction to combine water and air. In addition, this combination results in the generation of fine mist that has many functions.
Also, the nozzle is an essential aspect of any atomizer. Plus, the nozzles can be metal or plastic, allowing air and water in the atomizer.
So, when air and water reach the nozzle, water begins to break down into smaller droplets while mixing with air.
Indeed, there’s also something called a Venturi at the end of a nozzle. Interestingly, the purpose of this device is to fasten the mixing and dispersion process.
But note that atomizing here doesn’t refer to breaking down liquids into atoms. Instead, it includes breaking down liquid into smaller and finer forms and suspending them in other mediums.
As earlier stated, the nozzle of a water atomizer is a crucial part. It plays a huge role in the whole water atomization process.
Hence, there are various nozzle and atomization types that bring about various water atomizer applications. These types and their applications include:
Pressure atomization disperses water into fine mist via high pressure. Interestingly, you can use this atomization method for chemical or water sprays. Also, you can spray insecticides and herbicides with this atomization process.
It also works for controlling dust, acid gas, and particulate emissions from power plant cooling towers.
These atomizers utilize the electrical field between a grounded workpiece and an atomizer to break water into smaller drops. So, you can use them for applications that require propelling droplets on any surface.
You’ll find these kinds of atomizers where there’s a need for fine metal powders. The two-fluid atomization process combines air, water, and inert gas or oil to break molten metal or water into minuscule particles.
Two-fluid water atomizers can work in fire suppression applications. They usually combine high water pressure and compressed gas to generate mist.
The Ultrasonic atomization breaks liquid into smaller droplets with vibrations (high-frequency). Interestingly, you can use these water atomizers for applications like drying liquids with powder.
It also works for some medical applications that require controlling the speed of any fluid, vibrational frequency, and air velocity.
Here, we have a spinning disk that uses centrifugal force to disperse water into droplets. These water atomizers are great for applications that require spraying on a particular material only.
Water Atomizer Project
A smart humidifier is one simple project you can build with a water atomizer. It only involves a few connections, and its main component is an Arduino board. Let's take a closer look at how to build this project.
Here are the components you need for this project:
- Breadboard jumper wires
- LCD (16*2)
- Grove - water atomization v1.0
- Arduino Uno
- Humidity/temperature sensor module
- Momentary pushbutton switch
How it Works
The smart humidifier senses the humidity and temperature of its environment. If it senses the humidity or temperature is not within a comfortable range, it activates the humidifier for ten seconds.
Indeed, the circuit repeats the process until the temperature or humidity is in a comfortable range.
Making your Connections
It's easy to build this project. Simply follow the schematics below to make your connections.
Note: While drawing the schematics, there was no water atomizer on the fritzing part list, so we used a Grove-buzzer module instead.
The connections are similar, and you can think of the buzzer's signal pin as the water atomizer enable pin.
Upload your Code
So, it's time to upload your code to your Arduino board. You can download the code for this project here. Simply open your Arduino IDE and paste the code.
If everything is correct, you should see the following result:
It should also display the temperature and humidity on the LCD.
Connect your Water Atomization System
Once everything works, connect your driver board to the Arduino. Then, join your ultrasonic transducer to your driver board.
Take a glass cup filled with water and a piece of tissue paper. The tissue will help the transducer to receive water from the cup. You can also use paper towels.
Then, place your ultrasonic transducer on the tissue.
Test your Circuit
Once everything is complete, you can turn on your system. If the circuit produces vapor, then your circuit is working properly. You need to check your connections and code if it’s not working or consider replacing some parts.
In truth, there are other projects you can build with a water atomizer. So, they include a scent emitter, digital scent technology, and an AGPTEK mist maker.
So, water atomizers are fantastic devices that have various applications. Plus, they can help create a comfortable environment during the winter and summer.
You can also use water atomizers for agricultural applications; cleaning fruits or spraying pesticides or herbicides.
In addition, there's nothing complex about the water atomizer, and you can create easy projects.
So, what do you think about the water atomizer? Would you like to build or buy one? Do you have any questions? Please let us know.
