Job is to architect the system below using Arduino or Raspberry Pi, and describe the steps of what parts to buy and steps to building it:

I need to create a prototype to show the following:

1. When a full bottle of water (100% full) is placed on a pressure/weight sensor the system registers for example the capacitance and will either register and store that information or send it to a smart device via BLE or WiFi, it goes into passive mode after sitting on the sensor for more than 10 seconds to save power if possible. When the products weight is about 10 - 20% of starting weight, the system will register such and send the message to the smart device that only 10-20% is remaning.

2. I would like to use either Arduino or Raspberry Pi to demonstrate the above functionality with several weight sensors:

a. Tekscan Flexiforce A40-25, A-201-1 and A201-25

b. Capacitance sensor cut from aluminum and polymer

sensor film, we can use [url removed, login to view] for demo purpose.

3. Weight from 50g - 5000g

4. Size: 1" diameter to 4" diameter max

5. Hookup to a 9v battery and USB for MAC. USB is not absolutely necessary
