4Pcs USB Humidifieration Atomization Disc Micro Interface Atomization Drive Circuit Board DC 5V for DIY Home

The media could not be loaded. I selected this supplier from hundreds of other options after spending a significant amount of time of scrutinizing reviews of hundreds of other options. My observation is these ones perform top notch for the spend after rigorous testing. Be advised the transducer will burn through 8 ounces of water in a few hours. My use for these is to build aromatherapy device to atomize organic essential oils into the air. One that will not crap out in a few weeks or months, nor burn your house down.

I’m using these as individual plant humidifiers in containers of water. The first batch had 2 with broken wires at the soldered points. Our soldering iron stopped working last year and we’ve had no reason to replace it so couldn’t fix on our own.Customer service was very helpful and sent out another set to be delivered the next morning! Thankfully these worked well and all the plants are happy to have the extra humidity.These were a good deal overall and should serve the plants well during the dry winter this year and possibly next as well.

Have 2 running currently and they produce more than enough humidity for my small closet nursury.Features I would change if I could.The piezo wire is too short, since the card must be kept dry it would be nice if it were longer to get the electronics away from the humidity.I would also provide another alternative option where there is no button, and no auto shutoff, and have it directly controlled by incoming power so that one can use a smart hygrometer controller.

I've bought another atomization disc that only came with the circuit and disc which made it very finicky and broke easily. This atomization disc with its added accessories works very well and is very easy to use! They come with instructions and are well-packaged. I also like that the price is very affordable!
