Chapter 5: Practice – Multisensor for Your Room

Practice is the key to attaining a new skill, and this especially applies to developers. We have covered many topics in the first four chapters. Starting from using ESP32 general-purpose input/output (GPIO) pins, we have learned how to communicate with sensor devices, how to drive different display types, and—finally—advanced features of ESP32, such as ultra-low power (ULP) and power management to develop outstanding Internet of Things (IoT) products. There are endless numbers of sensors and actuators, but the communication methods and techniques for them are limited. As long as we have some degree of proficiency with those methods, we are good to go in many IoT projects. This chapter is a great opportunity to practice what we have learned so far by combining several sensors into a single device—a multisensor.

In this chapter, we will cover the following topics:

• Feature list of the multisensor
