They equipped the drones with compact sensors to provide data at nearly any time at a

three-dimensional axis. This important feature can help in reducing of sensors installed in the

ground-based monitoring system used in other smart city projects. Thus, reducing the total cost

of monitoring air quality. Additionally, the system allows the user to collect data for production

monitoring, issue discovery, and local climate control.

The project needed a wireless sensor network with the listed requirements: portability, low

cost, must be capable of storing data, and its wireless transmission. ...
