Esp32 control Atomizer Disc, for diy oil diffuser

ESPHome
1

In theory its possible to control those tad small atomizer disc from amazon with an esp32 (These Thingies) end goal is to 3d print a full open source air freshener for the bathroom, im thinking outside the box but imagine an oil diffuser with Dyson fan to flow it out further is my goal. All that is easy except im new to esp32

I have my newly installed presence sensors controlling my bathroom fan via sonoff relay, to turn on if presence for more than 1:30 minutes. Works well lol. But now we need a way to freshen up the space.

any tips?

I have played with these things in the past to diffuse oil its okay for ambient scenting, but i never tried putting fabreeze in it and see how it performed :slight_smile: hopefully i dont murder myself and my roomate with this invention

Connect esp32 to the button of that board and are good to go.
You should measure if that button switches GND or 5V to the chip on board.

Based on your measurement, you need some safety measure/external component as well. Esp is 3.3V MCU.
