As IoT technology evolves and machines become smarter and more capable, the need for human intervention will reduce. Machines will be able to autonomously respond to alerts generated by other machines.
In this chapter, you are going to build an energy conservation system that will show how two machines can communicate. Figure 11-1 shows a high-level diagram of all components involved in this system. The first component is an Arduino device that monitors light brightness levels and sends an alert whenever the levels are low. The second component is an MQTT ...
