What's impressive is that you can get a sensor for temperature, air pressure, "air quality", and humidity for $12.80 in quantity 1. "Air quality" is strange. It measures volatile organic components, not CO, CO2, or particulates. Sensors for those cost much more. So this is measuring what's easy to measure, not what's useful for, say, HVAC control.
8GB and Docker, plus a "cloud" server, seems a bit much.
