Sentrollers in the Internet of Things. The current Internet is an Internet of people, based on people communicating with people, using smartphones, tablets, laptops and computers. But this is changing: equipment and devices connected to the Internet (e.g. set-top boxes, cameras, cars) are starting to shift the balance away from people towards things. The future is clearly moving into a direction where the number of things connected to the Internet will overwhelm the number of connected people. Predictions range up to a factor of 100 to 1 or more: the Internet of People will transform into the Internet of Things.
Many of the new things connected to the Internet will be Sentrollers. Sentrollers are either actuators, sensors, controllers, or combinations of these three things. One simple example is a home thermostat. A thermostat is a sentroller as it senses the temperature in the home, checks whether the home or room in which the thermostat is monitoring temperature is at the desired temperature, and if not, turns on the heater or the air conditioner. Therefore, a thermostat is a sensor and a controller – a sentroller. No human interaction with the thermostat or the cloud will be necessary for the thermostat to keep the heat in the home at the right level.
