Hardware and software requirements

As always, we are going to start with a list of required hardware and software components for the project. We are going to use four modules in total: a sensor module, an appliance control module, a motion sensor module, and a camera module.

Of course, you will need one Raspberry Pi Zero board for each module you use, along with supporting components, such as SD cards and power supplies. If you plan to run the central interface on a Raspberry Pi Zero as well, you will need an additional Pi Zero board.

For the sensors module, we'll use a simple DHT11 sensor, along with a 4.7k Ohm resistor.

For the appliance control module, we'll use the PowerSwitch Tail Kit that we already used in several chapters of this book.

For the motion sensor module, we'll use a simple PIR motion sensor.

For the camera module, we are going to use the C270 HD camera from Logitech. However, you can use any USB camera here.

You will also need the usual breadboard and jumper wires.
