The PurpleAir Flex is one of the latest air quality monitors from PurpleAir, measuring real-time PM2.5 concentrations for residential, commercial, or industrial use. Containing a full-color LED, the resulting glow indicates real-time air quality at a glance and can be installed indoors or outdoors. Built-in WiFi enables the air quality monitor to transmit data to the real-time PurpleAir Map, which is stored and made available to any smart device.

For locations with limited WiFi access, the PurpleAir Flex PM2.5 measurement device incorporates real-time clock and SD card capabilities, allowing the sensor to record and store data on a microSD card.

The PurpleAir Flex features user-replaceable PMS6003 laser counters and an expansion port that allows easy swapping of the temperature sensors (yes, there are two) or expands the sensor's capabilities in the future.

Please note: This sensor does not come with a power adaptor. Find a suitable OUTDOOR-rated adaptor here or use your own USB power source (any 5V, 1.2 to 2.4 amp adaptor will work).

The FLEX sensor does not come with an SD card. Any card up to 64GB, class 10 or better will work, and must be formatted with a FAT32 file system. If you need a pre-formatted SD card, you can find one here.

Works right out of the box!

I mounted the device on my shed facing north and under the eve fascia boards to protect from rain and sun exposure. Air flow around the device is good and AQI is similar to another Purple Air device quarter mile up my street. WiFi signal is strong to my router, life could not be happier. Customer support is first rate.

PRIVATE SENSORS

I modify registration from public to private and I cannot see them on the map unless I used the registration mail and only shows one by one. Nor associated email or owners email could see them as the sensors we owned.

Wonderful tool but needs more interface options

I'm really happy to fill a giant gap in my state's air quality monitoring with this device. It was easy to set up and install out on my balcony, and I love looking at it sitting there on the map - the only one in my entire city. My one regret it that it's rather awkward to see the wide variety of things it's sensing - I have to go to a different layer of the map for each one. I'd really like the option to be able to pull up a single webpage where I can see my monitor in total - every single thing it's measuring at the same time on the same sheet. Maybe that's possible somewhere I just haven't found yet, but currently it seems like a noticeable lack.

Okay

I like the monitor and it was easy to set up. I thought the monitor would be able to show a breakdown of different types of pollutants but it doesn't seem to do that.

Hello,

We're glad you like the monitor. But just to clarify, yes, it cannot differentiate between different types of particulates.
