Overview of this book

This book is designed to introduce you to IoT and Raspberry Pi 3. It will help you create interesting projects, such as setting up a weather station and measuring temperature and humidity using sensors; it will also show you how to send sensor data to cloud for visualization in real-time. Then we shift our focus to leveraging IoT for accomplishing complex tasks, such as facial recognition using the Raspberry Pi camera module, AWS Rekognition, and the AWS S3 service. Furthermore, you will master security aspects by building a security surveillance system to protect your premises from intruders using Raspberry Pi, a camera, motion sensors, and AWS Cloud. We'll also create a real-world project by building a Wi-Fi – controlled robot car with Raspberry Pi using a motor driver circuit, DC motor, and a web application. This book is a must-have as it provides a practical overview of IoT’s existing architectures, communication protocols, and security threats at the software and hardware levels—security being the most important aspect of IoT.

Wiring up

So far, we have discussed all the components of our system in detail and now we will wire up all the components together with the Raspberry Pi, one by one.

Interfacing PIR sensor module HC-SR501

Refer to Figure 6.15 for connection details:

Figure 6.15

As shown in Figure 6.15:

  • The ground terminal of the PIR sensor is connected to the ground pin of the Raspberry Pi GND (Pin 06)
  • The output of the sensor is connected to GPIO 19 (pin 35) of the Raspberry Pi
  • The Vcc terminal is connected to +5V (pin 04) of Raspberry Pi
