Building a kiosk for Home Assistant from scrap parts - Part 2

With a project of this type, the hardware preparation is just the tip of the iceberg. It was thoroughly explained in the last post, despite one last change still being pending. What lacks is basically the addition of a resistive touch panel to the front of the screen, in order not to depend on the mouse as a pointer/input device. The panel is still somewhere between China and my location..

The first aspect that I found important to cover, now that I had this Android based kiosk up and running, was the ability to remote control it and launch arbitrary applications and services on startup.

It is great to have automation in the house providing increments of comfort such as eliminating manual tasks like cleaning the floor, or to aid in managing the energy consumption by turning off lights and appliances which are not in use, or in the safety side, by providing intrusion detection or monitoring the presence of gas leaks or other hazards, and executing the adequate actions.

Tasmota-based multi-channel air quality sensor station

The sense of smell is an amazing function in vertebrate animals. Even the human nose, which is not particularly notable in comparison with other animals, is fascinating in its sensitivity to trace amounts of a large variety of substances. It has a level of selectivity and capability of distinguishing between different kinds of smells, which is very difficult to match by even the most sophisticated artificial sensors.

Having as the main motivation the enrichment of the IoT gadgetry sitting around in my house (and eventually fill up an entire 192.168.1.1/24 network address range), I found that (after the motion and entrance detection device), an interesting device to invest time on would be something capable of sensing multiple air quality parameters at the same time.
