During our journey through this chapter, we discussed IR sensors, PIR sensors, and ultrasonic sensors in detail. We have also learned how to use Raspberry Pi camera module and how to send email notification programmatically; finally we stitched together all the components to build a security surveillance system. Now, we can go out without worrying about the security of our home in our absence.
In Chapter 7, Image Recognition, we will learn about face recognition techniques and build a face recognition system using Raspberry Pi.
