(due to insufficient DIY time, the upper humidifier shell was modified from ready-made DIY, and cannot be used for commercial purposes)
 
1. Display temperature and humidity through OLED, and change modes with buttons.
2. Mode 1 changes the RGB color according to different humidity. The RGB color of the humidity difference can be changed through software and can be burned through typec (for example, very wet is dark blue, moderate is green).
3. Mode 2 changes the RGB color according to different temperatures. The temperature difference RGB color can be changed through software and can be burned through typec (for example, very hot is red, very cold is blue).
4. Mode 3 customized RGB light show.
5. Set a humidity value (currently set to 80%), and turn off the spray when the humidity is reached.
6. Automatically shut down the spray when there is water shortage.
7. A small fan or light can be connected externally, and the speed can be adjusted through the knob.
