'MySensoring' a GE Washer
-
This is another very simple "Wash Cycle Completed" sensor. It's design uses the same Optocoupler sensing design I used in the Kiddie Smoke Detector project. The only difference is that I'm using 1 AC to DC transformer, and a boost module to boost the washer speaker power to fire the Optocoupler.
Parts:
- 1 Cheap AC/DC converter
- 1 Optocoupler
- 1 Step up Regulator
- 1 Small Proto Board.
- Some wire
Highlights:
Use the Washers .5vdc Signal Piezo to interface with the Pro-Mini. The voltage to the Piezo is to low to drive the Optocoupler so I had to use a boost module to boost the voltage to the Optocoupler. I'm not sure what the long term effect will be on washers control board Piezo drive circuit, so I will follow up if I encounter a problem.Again Uses the same sketch as the Kiddie Smoke Project, with the only change being to CYCLE_INTERVAL (For my dryer 3 works well)
