Although significant use of cell phones and internet provide accessible data for most people, some still do not have access to these resources. As an option for these people, DR DAS provides Voice Manager for integration with Envista ARM, or as a standalone interface to AirNow Data Downloads. When used with Envista, a programmable interface presents a friendly way to create a custom interactive script that provides a user the ability to select their region or station for Air Quality Index values. As a standalone product, the only difference is that the reported Air Quality Index values are only available at the region (and not the station) level. Part of the purchase of this product is a voice card that provides integration from the computer to your phone line.
