During this session, we first decided to digitize our project by converting our wiring diagram to an EasyEDA file and writing down this proposal of the whole project :

Whole schematic

For the general project in the Iot city we want to provide a system in which the trash cans of the city are connected to an app that the sanitary department uses. In this case each trash can would have a sensor to identify the capacity in which it is at present time, this meaning to know when it is about to be filled so it can be emptied before litter hits the ground.

The sensor will send a signal to the app when the trash can reaches 75% of its capacity so the driver can be notified that in a brief time it will be necessary to pick up the trash. Once it reaches 90% a notification will arise that it is time to pick up the trash, simultaneously it will identify the other trash cans in the area that also need to be taken care of. Due to the fact that each sensor has an integrated GPS to it, a path will be generated so the driver knows what streets to take in order to optimize time and make the route as efficient as possible.

In an ideal system trash would not have to be on the floor because there would always be space in a trash bin to put it, avoiding soil pollution and helping the environment.

Nowadays there is a device that has one of our features called: Bin-e. But it is used only to monitor the capacity of the trash can and the different trash types.

There is also a company that sells sensors that monitor trash in Slovakia called “Sensoneo”.

Then, we started wiring the device to create a first version of the prototype :

For next week, we'll have to start creating the box and the cover to puit over the trash can, dealing with the material resitance of the box and find a way to fix it.
