IoT Project postmortem
0 likes285 views
The document discusses a postmortem of an IoT project, detailing its objectives such as movement detection, real-time data transmission, and GPS tracking. It outlines the challenges faced during implementation, the components used (Arduino, Raspberry Pi, various sensors), and both their pros and cons. Future work is suggested but remains uncertain.
