3Pcs USB Humidifier Module USB Spray Module Circuit Board Atomization Module 5V Atomization Plate Circuit Board Atomization Module Atomizer DIY Incubation Experimental Equipment

Was buying nebulizers at over $50 each and after several months they would die. Decided to try this and put the piezo in the head... sure enough a exact fit. Bent the first one by not being careful, but worked perfect on the second try.

I love these! They are a great size, and so versatile, and easy to use. They were easy to assemble, and set up for my purposes only took about a half hour to figure out. I set them up yesterday, and so far, they are working great. I used one in my table top chicken egg incubator to keep the humidity where I want it. Most of them do not have humidity control, only monitoring. They use water storage of different size surface areas in the bottom of the incubator and rely on evaporation and surface area of the water to keep the humidity in the right range. But this can be difficult sometimes with people living in different climates. I am keeping the smallest water section full and stuck the wick down through the grid on the bottom into the water. I have this connected to a humidity controller and it's working great! I used another one in my little wine refrigerator where I store hatching eggs until they are ready to start incubating. It's good to keep them at 75% humidity. I don't have a controller for that one yet, so I am periodically turning it on for a minute. I have a humidity monitor with a probe that goes inside so I know what the humidity level is. I have a couple of Swedish cloths/sponges laying flat on the bottom and saturated them with water. The wick is sitting on top of one of those. That is working well so far too!

My husband wanted these to see if he could create a large humidifier that wouldn't be an incubator for mold. So far, he has succeeded. He made humidifiers for both bedside tables, and its wonderful to not have to drag a giant plastic bucket into the kitchen for de-molding on a daily basis. The only downsides are 1. the bright blue lights (you know, blue light, that thing that has been proven to be stimulating and bad for bedtime) and 2. the fact that they can't use USB-C cables with them. If you're interested in these, prepare to buy Micro-USB cables to use with them.

I'm using this to atomize neurotoxin for a Portal/GLaDOS themed project. Some things I really like about it: * The piezoelectric disc wires connect to the circuit board via a very reliable IDC connector. On other brands I've purchased, the wires are soldered directly to the PCB and break off easily. * The wick is VERY effective at providing the disc just the right about of liquid. * The PCB has through-hole pads on it for connecting your own power, and SMT pads to solder-jumper the switch to be permanently on. This makes it easy to control from a microcontroller. * The PCB has mounting holes to easily attach it to a project. Really the only downside I've encountered so far is that the LED is blue and very bright. I wish it could be easily disabled. Power usage at full steam is 250mA @ 5V. For others who might get it: When assembling this, the white ceramic ring side of the disc goes up (opposite the tube assembly). Also, before clipping the two halves together, make sure the wires are going through the correct side. Only one side has a gap for them.

The boards and the piezo work fine, however the incorrect paring of plastic shells which hold the foam wick meant that only one set could be assembled. As I will eventually be using this without these enclosures, it wasn't a deal breaker but frustrating that the seller couldn't be bothered to pair these up with putting them into the package. NOTE: The USB plug the older USB micro plug format (not USB-C), so any plug-in USB cable will need that size connector. Nowhere is this indicated in the packaging, or when ordering, so plan according before purchasing.
