You cannot cook IoT without these three ingredients

When my elementary school going son walks out to his bus stop in sub-freezing weather, as a parent it is comforting to know that he does not have to wait more than a minute or so for the bus.

The school bus now has a GPS tracker which coupled with a smart phone app will tell him exactly where the bus is by the minute and he only walks out when it is time to step out. This is the magic of three technologies: sensors (in this case GPS tracker), connectivity (the satellite link) and some rudimentary “analytics” (the smartphone app).
