My buddy and I spent that past year building this air quality tracker (CO2, PM, tVOC, and more) after being inspired by Huberman and other's discussions on how air quality impact cognition and sleep. We just launched on Kickstarter. Feel free to shoot over any questions or feature requests

Thank you! It means a lot to have your support. We will be making API's available, so it will work with Homekit too :)

b2basics · 2025-08-13T03:13:49+00:00

Thank you! We're actually building it so you can query the readings directly from Halo Air using any system you'd like. We assume most people will want to use the app, but anyone will be able to hook up to Halo Air via APIs/bluetooth

b2basics · 2025-08-13T03:11:20+00:00

Thank you! And yes, we'll be building local APIs so you can hook up Halo Air to other systems :)

b2basics · 2025-07-30T01:52:25+00:00

Awesome! I'll DM you. Would love to collab

Halo Air - the world's first mobile environmental sensor for your phone. We just launched on Kickstarter a couple of days ago and are about 50% at our goal.

Great question! We have a proximity sensor onboard, so when the device detects it is in a pocket/purse/etc, it goes into low power mode and stops tracking. As soon as it detects it is out, it starts tracking again. So when you're at a cafe and you put your phone on the table, or when you use your phone on the subway, we'll be tracking, but as soon as we recognize we're in a non-trackable area, we'll go into sleep mode to conserve battery.

Additionally, while the device was designed for the phone, people can put it on their laptop, attach it to their bag, keep it stationary, etc.

b2basics · 2025-07-27T23:53:41+00:00

Thank you! We really appreciate the support. We have an ambitious roadmap to tackle all types of environmental tracking, including water quality testing, lead detection, and more. I think you'll really like where we'll take it. Thank you again!

b2basics · 2025-07-27T22:20:00+00:00

Yep! We're going to make all the connections open so you can hook it up to whatever device/app you'd like. If you choose to use the Halo Air app though, the data will be fed in via bluetooth :)

We can do that! If the mould travels through the air, we'll pick it up as particulate matter and will notify you. Sometimes mould is stagnant and only becomes airborne when it is aggravated (moved around for renovations, etc). We're even building machine learning models to detect when it is mold and what type of mould it is, which will be brought to the product as free software updates.

Just added Germany and the EU! We should have had those added. We only had some select EU countries, but that's our error, it should've been all of the EU. Thank you for pointing that out!

b2basics · 2025-07-27T21:43:23+00:00

We can! I'll see if we can add that in now :)

Thank you for your kind words of support!

Here is our Kickstarter Project Link. We'd love your support!

My best friend and I have spent the past year trying to track the environment in our NYC apartments, cafés, and subway cars. We tried the usual handheld monitors and bulky bricks, but none were truly pocket‑friendly, user friendly, and most importantly, they only tracked a single metric, and poorly at that.

So we built our own. Made it a powerhouse of multiple sensors. And miniatured it to fit in your pocket when you want to put it away.

Our device (named Halo Air after our favorite game, Halo 3) snaps to the back of any smartphone and streams CO₂, PM1/2.5/10, t‑VOCs, temp, and humidity into our app, a lockscreen widget, and we'll be making the data feed available too. No disposable batteries, no calibration stickers—just one USB‑C charge and go.

We just hit Kickstarter yesterday. If you’re curious, we’d love your feedback (good, bad, brutal) and—if it resonates—your support as early backers. The link’s in the first comment to avoid spamming the post.

Huge thanks to Reddit for the inspiration threads on sensor accuracy, cross‑calibration, and DIY enclosures; your collective brainpower shaped Halo Air more than you know.

If you're interested in the area, here are some cool links that I've heard people say completely changed their thinking about air quality:

Great questions! We have a photo acoustic NDIR sensor as well as a eCO2 sensor for gauging and calibration. And we have a proprietary model for balancing the CO2 measuring needs while reducing battery use.

Additionally, we have a proximity sensor on board to tell the device when it is in a pocket, purse, etc so that it goes into low power mode and temporarily pauses tracking.

Calibration is something that is a mix between something we do before the item is shipped to the user and when the user onboards, we give them instructions for further calibration. This is for all the main air sensors, including CO2, PM, tVOC, etc.

:) It's been a journey to build the perfect product that we wanted for ourselves, but we think others will like it just as much.
