PurpleAir Zen Air Quality Monitor

  The PurpleAir Zen is the latest air quality monitor from PurpleAir, measuring real-time PM2.5 concentrations for residential, commercial, or industrial use. Containing a full-color LED ring, the resulting glow indicates real-time air quality at a glance, whether used indoors or out. Built-in WiFi enables the air quality monitor to transmit data to the real-time PurpleAir Map, where it is stored and made available to any smart device. Please note: This sensor does not come with a power adaptor. Select a suitable indoor or outdoor-rated adaptor above, or use your own USB power source (any 5V, 1.2 to 2.4 amp adaptor will work).
