Because of the area limitation of this FSR, I used an apple and a bottle of juice to mimic different packages.
After turn on the switch, first I placed an apple on FSR and one LED shine; then I placed a heavier bottle on FSR and two LEDs shined. The two values of force are displayed in Cloud. By using this device, users can detect whether their package has arrived by LED signal inside home and predict which order through force value. The process is shown in the video below.
For future improvement, I want to have push notification on mobile phone by using IFTTT. Also the prediction of package could be more useful and accurate by connecting the weight information from website like Amazon with this device.
