Air Quality Monitor with LoRa Interface

Hi, I’m in the middle of choosing a final year project for college.
One that caught my eye was to develop a Low-power air quality monitoring system based on LoRaWan technology.

I presume I would need a large number of air pollution sensors within a certain distance of eachother in which the data received is used by LoRaWan to send / save data to the cloud.
There would also need to be some sort of GUI implemented.

The goal is to develop a low-cost, long distance and easy to operate system that will also need to be able to run for a long time.

I just want to know would this project be a lot harder than it sounds, and what way would I need to go about it.

Any help is appreciated.
