The estimated setup is as follows:
* Rpi will be stacked with Rpi cam, PICO HAT Hacker PCB, PIM486 Enviro HAT, and PIM487 Automation HAT.
* It will contribute to roughly
L * W * H as 86 * 57 * (25 + 17 + 9) = 86 * 57 * 51 (mm)
= 250002 mm^3 ~ 250 cm^3.
* The additional mini water pump, microheater, LED lighting, power cable with a splitter, and miscellaneous could contribute to roughly another 750 cm^3.
* So total footprint for a single control module is
250 + 750 = 1000 cm^3 ie, 0.001 m^3.
* So we can accommodate
1/0.001 = 1000 units into the available 1m^3 space.
* To put forth in perspective, we can have 1000 of our control units managed in the available space.
