Hello @Val

PurpleAir sensors measure air quality at a point rather than an area. You could find multiple suitable locations to place the sensor, but more sensors will be needed if you want more coverage for an area. More information can be found in our [Sensor Coverage Area](https://community.purpleair.com/t/sensor-coverage-area/124) article.
