Source: http://www.centrinity.com While I was running for my life, after I exited the Lekki Treadmill and jogged into Alexander Road, Ikoyi, Lagos, Nigeria, I came across a 20ft "portakabin" container that seems to be someone's place of abode. I figured out that he is the one manning the generator that powers the street lights for Alexander/Bourdillon roads. I thought to myself, what if this man's job can be performed by a series of IoT devices and this man can be gainfully employed somewhere else which will allow him sleep comfortably in a bed under a real roof. What does he do? He switches on the generator when there is no public power and switches off the generator when he is aware that public power has been restored He switches on (or ensures this) street light when it is dark he is the first responder if there is an issue on site However, let us evaluate replacing that function totally with IoT devices: Automatic Generator Start/Shutdown:
This showcases the use of IoT devices in solving everyday domestic and business technology problems. Raspberry Pi is the primary tool.
