Building an IoT alarm module case
As we have done previously, we will install our components into a custom-designed 3D-printed case. Figure 6.21 features a rendering of our alarm module case, designed to accommodate the PIR sensor, buzzer, LED with a resistor, and the Raspberry Pi Pico W.
In the interest of compactness, we’ve opted for the Raspberry Pi Pico W without headers, simplifying component fitting and wire soldering. It’s important to note that this choice is optional, and we can use the header-equipped Raspberry Pi Pico WH:

We will start by identifying the parts before we move on to constructing and then testing our IoT alarm module.
Identifying the parts of the custom case
In Figure 6.22, we can see the parts required to assemble the custom case for our IoT alarm module:
