Description and photos can still change, design files are already final and system is operational on the desk
 

A connector for the exhaust tube to the outside is not yet designed.


The original S.O.G did not fit my requirements.

  • smart controll via M5stack controller
  • allow different speeds for “in use” and “already filled”
  • fan shall be quiet in permanent operation
  • cheap supply of filters
  • shall be able to intelligently detect, first use, shutter closed and repeated use

Implementation:

  • use the S.O.G supplied upgrade for Dometic toilettes without fan and filter
  • implement a M5Stack based sensor using S.O.G parts
  • design housing for Noctua NF-A9x14 PWM controlled PC-fan
  • use carbon filter mats
