1. My letterbox Stop waiting for your letter, be aware of its delivery

2. 1. A new letterbox? Bringing remote monitoring to your daily routine

3. General description - Needs
We’re living in a connected world where people want to be aware of everything.
As everything cannot be digitalize we need to upgrade our aging letterbox to stop checking and waiting for letter or parcel.

4. My letterbox will help users managing their daily deliveries of letters and parcels

5. What we tried to achieve
What are the expected features?
What we tried to achieve

6. Expected features Get the amount of letter in your letterbox
Set a threshold before withdrawal
Say if you’re waiting for a parcel
Be notified of letterbox activity: whether the door has been open and if you’re threshold of letters has been reached

7. 2. My letterbox What’s inside of the box?

8. Upgrade your actual letterbox
Add 2 sensors and a raspberry Pi
Take your smartphone
That’s all.

9. Which sensors?
A sonar & hall sensor

10. Disposition of your sensors Sonar sensor Hall sensor Magnets
Raspberry Pi

11. The user interface?
THe simpler, the better

12. User interface Smartphone are widely used. Let’s develop a mobile app

13. User interface

14. User interface But it’s not enough, we want no jealousy

15. User interface

16. User interface Supported by both OS

17. Having an app is nice, bringing features is better
What are its actual features?
Having an app is nice, bringing features is better

64. Further improvements Miniaturize
Connect several sensors to the same raspberry
Support user account and possibility to subscribe for different letter box in the same application
