As always, we are going to start with the list of required hardware and software components for the project.
For the sensors, we'll use a simple DHT11 sensor, along with a 4.7k Ohm resistor. We'll also use a PIR motion sensor.
For the camera module, I will use a Logitech C270 webcam. Here, any camera compatible with the UVC protocol would work, which is the case for most of the cameras sold those days.
Finally, you will need the usual breadboard and jumper wires.
This is the list of components that you will need for this whole chapter, not including the Raspberry Pi Zero:
