Read more about IT Security Policy for Deployment of AirGradient MonitorsWe strongly recommend that you fully understand data ownership terms before buying an air quality monitor, as some of them can be extremely restrictive.
Read more about Data Ownership and SharingThe accuracy of an air quality monitor is impacted by a variety of internal and external factors, for example: - Enclosure: The ventilation and internal placement of sensor modules can greatly impact their accuracy.
