IoT Cloud key terms
In this section, we will cover some of the key terms that we need to understand before we dive into the details of the components offered by IoT Cloud.
State machine
A state machine is a device that can remain in one or more states. The change of state from one to another is technically known as a transition. The transition or state of change occurs in response to an external input.
State diagrams are used to represent a state machine's states and transitions. In IoT Cloud, the events that are emitted from the devices can be modeled into states and transitions.
Let's further understand states, transitions, and state machines with the help of an example. Let's assume we are monitoring events from the temperature sensors (assume the sensor is sending signals every second to the IoT Cloud along with data consisting of temperature readings). We are monitoring three primary states, as shown in the following table, and we want the system to automatically create a work order in...
