Building Smart Homes with Raspberry Pi Zero

By: Marco Schwartz

Overview of this book

The release of the Raspberry Pi Zero has completely amazed the tech community. With the price, form factor, and being high on utility—the Raspberry Pi Zero is the perfect companion to support home automation projects and makes IoT even more accessible. With this book, you will be able to create and program home automation projects using the Raspberry Pi Zero board. The book will teach you how to build a thermostat that will automatically regulate the temperature in your home. Another important topic in home automation is controlling electrical appliances, and you will learn how to control LED Lights, lamps, and other electrical applications. Moving on, we will build a smart energy meter that can measure the power of the appliance, and you’ll learn how to switch it on and off. You’ll also see how to build simple security system, composed of alarms, a security camera, and motion detectors. At the end, you will integrate everything what you learned so far into a more complex project to automate the key aspects of your home. By the end, you will have deepened your knowledge of the Raspberry Pi Zero, and will know how to build autonomous home automation projects.

Make a motion-activated lamp using IFTTT


In this section, we are now going to use what we learned in this chapter and combine it with what we already learned in the previous chapters about the web service IFTTT. We are going to use this knowledge to build a lamp that is automatically activated when motion is detected by a motion sensor.

For this section, you will need two Raspberry Pi modules: one with a motion sensor and one connected to a lamp via the PowerSwitch tail. To learn how to assemble these modules, please refer to the previous chapters of the book.

This is the assembled Raspberry Pi Zero with a PIR motion sensor on GPIO18:

We are first going to create the IFTTT recipes so you and the two boards can communicate. First, make sure that the Maker channel is activated on your IFTTT account:

Then, create a new recipe, with the Maker channel as the trigger:

For the event, enter motion_detected:

Choose the Maker channel as the action channel:

For the action itself, choose Make a web request...
