Using Arduino UNO as switch for Nebulizer

Hi there!

Im current working on a school project where i have to control the turning off and on of a Compressor Nebulizer through using Arduino Uno. I've figure that i would probably have to substitute the switch of the Nebulizer with a Arduino Uno. However im unsure about a few things.

  1. Can Arduino Uno handle the voltage and current
  2. How should I be connecting my Arduino board to the electrical boards?

Here are the specifications of the product:
Nebulizer: OMRON NE-C803
Power source plug-in : DC 6V
Rocker switch:


Micro Air Pump: KPM32F-6A01 DC6V

Do let me know if you guys need any more information!

Thank you!!

This can be accomplished with a relay controlled by the Arduino.

Hey thanks for the reply!

So would i just have to connect my Arduino board to a relay switch which will then be substituting my current rocker switch? Sort of like what is shown here https://create.arduino.cc/projecthub/techvaler/basic-setup-for-arduino-with-relay-e162d5

That’s about it.

So no, not exactly like the dreadful "tutorial" that shows how to drive an LED with a relay; but like this

which preserves isolation between the arduino circuit and the external circuit.

So to be very specific you should have no external connection between the left and right hand sides of the relay module.

Hey man! Rly thankful for the resources. Definitely have a clearer picture of what needs to be done now. Thanks!

Hi sir sorry for bothering again. I was wondering why the relay is actually required in this case. Is it because the voltage supplied by the source is too high? In this case the voltage is 6v. Or is something to do with the current being too high? I cant rly figure out the numbers as im not often exposed to dealing with circuitry. Seems to me the number (observed in the product phamplet) can be well tolerated by the Arduino UNO itself. Are we using the relay just for the ease of connection to an external supply source? Do let me know. And once again, thank you for your time.

No you can not draw 700mA from an Arduino.
