A sentroller, used in the Internet of things is a sensor, controller or actuator or combination of these three.
The current Internet is an Internet of people, based on people communicating with people, using smartphones, tablets, laptops and computers, but this is changing:[citation needed] 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.
In practice, sentrollers absorb and/or produce very limited amounts of information, but connectivity to the internet is essential for their operation.
The Internet of things will host the applications that know how to interpret the information provided by sentrollers and what action to be taken.
[dubious – discuss][citation needed] The sentrollers are the end nodes that will become the majority population of this type of Internet of things.
