Introducerade killarna till kylskåpet och gav dem 2 ESP8266 + 3 RPi0 + 4 Ultraljudssensorer + RPi4 med tillbehör
KIllarna förstod utmaningen, också avgränsningen.
Fokus är inte kylskåpssäkerhet, inte heller user interface design, inte heller lähimaksubetalningsintegration
Målet är att implementera en lösning där RPi0 kopplas till en ultraljudssensor per produkt.
Vi efterlyser alltså en lösning för monitorering av inventarie.
In order of importance:
Stop inventory from falling off the slanted shelves (the "gravity based autoloader")
3D models and basic documentation of mechanical implementation (3d print?)
Rough spec, can it take 10 soda bottles? How about kolmioleipäs?
Product specifications for the smart fridge
Are we planning to serve only sodas, how different is the challenge for certain food or snacks?
Sensors and microcontrollers mounted in fridge.
Sensors notice when product is removed.
What product was removed and how many.
Data is sent to a server or a phone (BT or Wifi)
Wireless implementation to avoid cables through fridge door
Log with timestamp and products
Great documentation, both developer and user docs (Wiki)
Possibility to enter management mode for refill
Some type of authentication
Notify when inventory is running low
Alarm when "payment" is not done
Laminated piece of paper with products and prices
If possible: display that shows producs and prices
Power management/monitoring
How long does one 20Ah powerbank last?
A simple risk assessment and eventual anti-scammer improvements
Remember we are not police, inventory is not that valuable...
Temperature monitoring
