After the experiment was carried out, several significant problems were found which would be material for further development:
Weaknesses acquired
- Data from DFROBOT cannot be received properly if it is transmitted more than 8 meters using cable,
- The occurrence of buffering and bottle neck on DFROBOT's "note point 1" transmission, which causes an infinity loop in the case logic.
- There are many failures in sending data using sim800l;
Improvment plan:
- Improved data transmission to the sensor to the motherboard using LoRa
- independent power addition in each sensor,
- upgrade using sim7600g
- take into account power consumption
- new board 💯
