DIY Air Humidifier: Improve Air Quality at Home

If you're eager to delve into the world of nebulizer discs, here's a fun project for you: create your own air humidifier using a USB-powered module.

Here's what you'll need: a straw, a driving module, and of course, the nebulizer discs themselves.

The nebulizer disc features a distinctive protrusion on its back, making it easily recognizable.

For the driving module, you'll require an 8-pin unmarked IC and a 3-pin S400 switch tube.

Additionally, gather a long press button, an LED indicator, and an inductor without markings for a complete setup.

Begin by repurposing a mineral water bottle cap: drill a hole in the center and insert the straw securely.

Next, connect the driving module and the nebulizer disc, ensuring a snug fit.

Fill the mineral water bottle with water and tightly seal it with the modified cap.

Now, carefully position the nebulizer disc atop the cap. Press the switch once, the air humidifier is working, press the switch again, the air humidifier stops working.

With these simple steps, you've successfully crafted your very own air humidifier from scratch.
