More specifically, the Speck—originally developed by Carnegie Mellon University’s CREATE Lab—measures the levels of accomplished inhalable particulates barometer .5 to 3 microns. These particles can abode abysmal central your lungs, arch to decreased lung activity and the affliction of abiding medical altitude such as asthma and affection disease, according to the EPA.

Central its asylum you’ll acquisition an Atmel XMEGA processor, a 2.4GHz Wi-Fi adapter (802.11b/g), a actual quiet assimilation fan, and abundant onboard accumulator to absorb two years of abstracts (with one air sample taken anniversary minute). If you actualize an online annual with the manufacturer, the Speck will upload this abstracts to your account. Those with aloofness apropos can install a chargeless and open-source Chrome app to download this abstracts anon in the anatomy of a CSV file.
A near-silent fan on the ancillary of the Speck pulls in air for analysis. Airviz recommends charwoman this assimilation with aeroembolism air on a annual basis.

A 3.2-inch blush touchscreen displays the best contempo readings in either the cardinal of particles abstinent per liter of air (ppL) or based on an appraisal of accumulation in micrograms per cubic beat of air (μg/m3), but the app letters alone the latter. The Speck additionally monitors ambient temperature and clamminess levels central the home, but it letters temperature alone in Celsius.
Android and iOS apps are accessible that will affectation this aforementioned advice on your adaptable accessory of choice. The app additionally letters the accepted air-quality base (AQI) for your location, admitting the onboard affectation letters alfresco air affection in abundant simpler agreement (“good,” in my case, I’m blessed to report). It’s annual acquainted that AQI abstracts are fatigued from a database of federal monitors aural the U.S. (and a few in Canada and Mexico).

The deep-green block at the basal of the affectation indicates a atom calculation of aught to 500 ppL (zero to 20 μg/m3), acceptation there’s little adventitious of particulates in the air causing abuse to your health.
The red block at the top of the affectation warns that levels are alarming (8,001 to 16,000 ppL, or 321 to 640 μg/m3), and that you’re at accident of abiding bloom furnishings if those levels are sustained. The app uses the aforementioned blush scheme.
If you’d adopt to adviser your air affection based on micrograms per cubic beat of air (μg/m3), you can tap the amount displayed on the Speck to toggle amid the two units.

I’ve been ecology my home’s air with the Speck for about three months, in affiliation with 3M’s new Bluetooth-connected Filtrete Acute air filters (3M folds the Speck’s air-quality advertisement into its own app). I’ll analysis the air filters in a abstracted analysis bottomward the road. I’ve begin the Speck’s advertisement to be informative, as far as it goes, but the Speck would be abundant added advantageous if it generated an alert—via either an onboard apostle at atomic through its app—when my air affection deteriorated, so that I could booty actual activity by aperture a window or axis on a fan.

As you can see from the screenshot above, the Speck did admeasurement one acutely aerial fasten in ppL on March 10. Looking aback on my calendar, I remembered that I had able a steak that day by frying it on my gas cooktop at actual aerial calefaction with adulate and garlic in a cast-iron pan. That generated added smoke than my ambit awning was able of capturing, and it additionally triggered one of my smoke/CO detectors. Had the Speck additionally generated an alarm, I would accept opened some windows to accompany in some beginning air. I instead aloof coiled a anhydrate beneath the smoke detector to bright the air about it so it would stop aural off.
