This project aims to create an open source smart collector. The objective of the collector is to collect plastic x=waste in the perspective to valorize it into a circular enconomy. The main function of the collector is to communicate the weight of its content.
- Measure the weight of its content
- Measure the state of the battery
- Send the information to sigfox backend
- Tare weight the empty collector before being filled
To have further hint about how the prgram of the device work, activity diagrams are available here.
- PYCOM SiPy
- Deep Sleep shield for SiPy
- PYCOM Expansion Board 3 OR Battery Management system TP4056
- LiPo Battery
- 5 Kg Load cell
- Analog digital converter - hx711
- Install VS code
- Install Pymakr add-on in VS Code
Pycom Hard reset when the microcontroller is not accessible

Factory reset your module to remove your code
>>> import os
>>> os.fsformat('/flash')
In order to update the firmeware without the board, the pin P2 has to be connected to GND. It is the bootloader mode USB serial programming
