In this chapter, we saw how to interact with different sensors connected to the Arduino board, such as flow current for energy consumption, detecting a risk in the home, implementing a gas sensor, implementing flow water sensor to measure the water volume, making a security system, and controlling access with a fingerprint sensor. All of these sensors can be integrate a complete system for monitoring and controlling everything you work on any project.

In the next chapter, we will see how to integrate everything for monitoring and controlling a complete system, and reading the sensors and actuators in a dashboard using your Arduino board and the Raspberry Pi Zero as a central interface.
