Morium — ESP32-Based UV-C Sanitizing Humidifier
The project began with the thought that a humidifier sitting idle for three seasons is a waste, so I am designing a small appliance that combines one with a moss terrarium and earns its desk space all year.
Documentation comes before geometry: every decision from requirements down to component selection is written before it is drawn.
Current Status
- Complete: product requirements document, system architecture and power budget, preliminary BOM, firmware state machine and safety logic, fabrication dimension reference, benchmark of hygiene technology in commercial products (six documents, published as PDF)
- In progress: adding drivetrain torque budget and tolerance review to the power budget document, detailed CAD
- Not started: prototype fabrication, firmware implementation
Design Constraints
For the UV-C sanitizing section, the light-shielding structure and interlock were fixed as constraints before the enclosure geometry was drawn.
Separation of the water and electronics compartments, automatic UV shutoff through a hardware interlock when the lid opens, and ultrasonic cutoff within 100 ms at low water level were all locked in at the requirements stage.
CAD
Key dimensions are parameterized in CadQuery, so changing a dimension regenerates the geometry and every decision stays in the code.
