Our most popular Notecard got an update. Learn more about the new Notecard Cellular.

Last month, we announced the Airnote, an air-quality monitoring device powered by our developer-friendly cellular technology and built in partnership with the Safecast team. It’s a powerful little device that can give you a picture of your local air quality, while contributing to global air quality awareness with the help of the Safecast network.

If you’re interested in a full hardware teardown and overview of the Airnote, check out the post and overview video I published on Hackster.

In celebration of IoT Day on April 9th, and Earth Day on April 22nd, we’re giving a handful of Airnotes away, and we want you to have one!

From April 8th to April 20th, we’re running a contest called Show us your air, Get an Airnote.


Here are the rules: Film a 30 second video that shows us where you’d place an Airnote, and why you want to measure the air quality where you are. Then, post that video to a sharing service like YouTube or Vimeo and send us the link by April 20th. We’ll send free Airnotes to the creators of the 5 best videos and announce the winners on Earth Day, April 22nd.

So what are you waiting for? Get that camera ready, share your best creation, and let’s raise the bar for air quality awareness together.
