Anyone else have an AirGradient Air Quality Monitor?
I got one last week and set it up in HomeAssistant but comparing it to my older PurpleAir sensor it shows much lower pm2.5 than the PurpleAir. I looked at both of their public maps as well and it tells the same story.
Is the AirGradient just a subpar device?
I hope not as I was happy for the open source firmware and local only connection to HomeAssistant.

Finally got some filters so I can get my house air cleaned out a little.
It isn't too bad out other than the smoke. The smoke is really bad very visible.

#AirQuality concerns dominate western #Colorado with incoming smoke
by: Dalen Brazelton
Posted: Jun 24, 2026 / 06:25 AM MDTGRAND JUNCTION, Colo. (KREX) — "Fires in #Utah and Colorado and smoke in the valley is causing massive air quality concerns. Chances for showers tonight will help soak up a lot of particulates in the air, but with near-100 degree highs today, most chances for daytime rain will evaporate. Dry lightning also remains a concern, with possibilities of it sparking another wildfire. Chances for storms jump to 60 percent tonight."

Here is why you should open your #windows whenever you can. On the left, is 2:05 PM when I’ve had the windows closed all day, the #CO2 levels in the house are high, indicating poor #ventilation. Now swipe to the right image, the levels have dropped to a third after leaving the windows open for over 2 hours, indicating excellent ventilation. High CO2 levels indoors can cause various #health issues including #tiredness, #headaches, #eye #irritation, #dizziness and/or #difficulty #concentrating, so please check your levels inside your house. I borrowed this CO2 monitor as well as an #AQI monitor from my local #library

We can't breathe
The Invisible #ClimateChange Effect That Is Most Likely to Kill You
#AirPollution is less dramatic than floods or storms, less inconvenient, and much harder to politicize. It’s also much more deadly.
Liza Featherstone, August 1, 2025
Excerpt: "In #NewYorkCity, I’m lucky enough to enjoy better air quality than many other places. We are only the fiftieth most #polluted city in the world, way behind #Chicago, #Dubai, #Jakarta, #Delhi, and numerous (enormously populous) cities in #China. But for a few days early this week, it was hard to breathe and our phones were buzzing with alerts warning that the most vulnerable—the very young and the very old, and those with poor respiratory health—should stay indoors, due to smoke from Canadian wildfires. But the elderly, the asthmatic, and the babies weren’t the only ones feeling it; my son, a college soccer player, got headaches training outside, as did his friends—all fellow rain-or-shine athletes. Yet for the most part, the problem has gone unremarked.
"Compared to a flood, a fire, or a heat wave, a bad #AirQualityAlert isn’t that inconvenient even when it’s happening. You can still go to work and otherwise go about your day. If you own property, it won’t be damaged. And because #AirPollution lacks visuals, it doesn’t lend itself to morbid #doomscrolling or panicked media coverage.
"Yet compared to floods, fires, and heat waves, bad air is much more deadly. In fact, the danger is barely even comparable. The World Health Organization estimates that air pollution kills about seven million people every year. The direct death toll from heat waves is under half a million, although that’s getting worse. The number of people who die in floods annually is in the thousands, and the direct death toll from wildfires is much smaller than that, though these threats are also getting worse. "

The smoke from #Canada’s #wildfires may be even more #toxic than usual
A legacy of #mining means that #ToxicMetals could be carried along plumes of smoke.
by Matt Simon, June 5, 2025
"More than 200 wildfires are blazing across central and western Canada, half of which are out of control because they’re so hard for crews to access, forcing 27,000 people to evacuate. Even those nowhere near the wildfires are suffering as smoke swirls around Canada and wafts south, creating hazardous air quality all over the midwestern and eastern parts of the United States. The smoke is even reaching Europe.
"As the climate changes, the far north is drying and warming, which means wildfires are getting bigger and more intense. The area burned in Canada is now the second largest on record for this time of year, trailing behind the brutal wildfire season of 2023. That year, the amount of #carbon blazed into the atmosphere was about three times the country’s #FossilFuel emissions. And the more carbon that’s emitted from wildfires — in Canada and elsewhere — the faster the #PlanetaryWarming, and the worse the fires.
" 'There’s obviously the #ClimateFeedback concern,' said Mike Waddington, an environmental scientist at McMaster University in Ontario who studies Canada’s forests. 'But increasingly we’re also concerned about the smoke.'
"That’s because there’s much more to wildfire smoke than charred sticks and leaves, especially where these blazes are burning in Canada. The country’s #forests have long been #mined, operations that loaded #soils and #waterways with #ToxicMetals like #lead and #mercury, especially before clean-air standards kicked in 50 years ago. Now everyone downwind of these wildfires may have to contend with that legacy and those pollutants, in addition to all the other nasties inherent in #WildfireSmoke, which are known to exacerbate respiratory and cardiac problems.
" 'You have there the burning of these organic soils resulting in a lot of carbon and a lot of #ParticulateMatter,' said Waddington. 'Now you have this triple whammy, where you have the metals #remobilized in addition to that.'
"What exactly is lurking in the smoke from Canadian wildfires will require further testing by scientists. But an area of particular concern is around the mining city of #FlinFlon, in #ManitobaCanada, which is known to have elevated levels of toxic metals in the landscape, said Colin McCarter, an environmental scientist who studies pollutants at Ontario’s #NipissingUniversity. Flin Flon’s 5,000 residents have been evacuated as a wildfire approaches, though so far no structures have been destroyed.
"But a fire doesn’t need to directly burn mining operations to mobilize toxicants. For example, in #Yellowknife, in Canada’s #NorthwestTerritories, #GoldMining operations between 1934 and 2004 spread #arsenic as far as 18 miles away, adding to a landscape with an already high concentration of naturally occurring arsenic. In a paper published last year, Waddington and McCarter estimated that between 1972 and 2023, wildfires around Yellowknife fired up to 840,000 pounds of arsenic into the atmosphere. Arsenic is a known carcinogen associated with cardiovascular disease, diabetes, and developmental problems, according to the World Health Organization. (After the 2023 #LahainaFire in Maui, officials reported elevated levels of arsenic, lead, and other toxic substances in ash samples. California officials also found lots of lead in smoke from 2018’s #CampFire.)"

If your area has nasty smoke right now and you are sick of having to keep checking a website to get the current AQI I made a small internet enabled LED project that glows with the current AQI color. Only needs a NodeMCU/Feather, a NeoPixel Jewel or Ring and some Dupont type wires to connect. See https://www.instructables.com/PurpleAir-Air-Quality-Status-LED-Display/ for really simple instructions and code. Code also here; https://github.com/jeff-luszcz/PurpleTheopolis #arduino #nodemcu #neopixel #aqi #smoke

My #airQuality monitor is finlazed with a temperature and humidity sensor. You can see on the graph when I was soldering. I'm glad I'm not doing that activity very often!
I am trying to categorize the sensor readings into ranges: perfect, healthy, average, bad, and terrible. However, I am having difficulty determining the ranges and a formula to categorize them using a single sensor.
Any advice?

Not just human health! The #Toxic Blend of LA’s Urban #WildfireSmoke Will Have Lasting Health Consequences
Los Angeles residents are breathing bits of "cars, metal pipes, plastics."
By Zoya Teirstein, January 22, 2025“These fires are different from previous quote-unquote ‘wildfires,’ because there are so many structures that burned,” said Yifang Zhu, a professor of environmental health sciences at the University of California, Los Angeles. 'Everything in the households got burned — cars, metal pipes, plastics.'
"#Wildfiresmoke is toxic. Burning trees and shrubs produce very fine #particulatematter, known by the shorthand PM 2.5, which burrow deep into the lungs and can even infiltrate the bloodstream, causing cold- and flu-like symptoms in the short term, and heart disease, lung cancer, and other chronic issues over time.
"But the fires that raced through Los Angeles burned thousands of homes, schools, historic buildings, and even medical clinics, blanketing the city in thick smoke. For several days after the first fire started, the city’s air quality index, or #AQI, exceeded 100, the threshold, typically seen during wildfires, at which air becomes unhealthy to breathe for children, the elderly, and those with asthma. In some parts of the city, the AQI reached 500, a number rarely seen and always hazardous for everyone.
"At the moment, air pollution experts know how much smoke fills the air. That’s shown improvement in recent days. But they don’t know what’s in it. 'What are the chemical mixtures in this smoke?' asked Kai Chen, an environmental scientist at the Yale School of Public Health. 'In addition to fine particulate matter, there are potentially other hazardous and #carcinogenic organic compounds — gas pollutants, trace metals, and microplastics.'
"Previous research shows that the spikes in unhealthy air quality seen during such events lead to higher rates of hospitalizations for issues like asthma, and even contribute to heart attacks among those with that chronic disease. A 2024 study on the long-term effects of smoke exposure in California showed that particulate matter from wildfires in the state from 2008 to 2018 contributed to anywhere from 52,000 to 56,000 premature deaths. A health assessment of 148 firefighters who worked the Tubbs Fire, which burned more than 36,000 acres in Northern California in 2017 and destroyed an unusually high number of structures, found elevated levels of the #PFAS known as forever chemicals, #HeavyMetals, and flame retardants in their blood and urine.
"The L.A. County Department of Public Health has formally urged people to stay inside and wear masks to protect themselves from windblown toxic dust and ash. Air quality measurements don’t take these particles into account, which means the air quality index doesn’t reveal the extent of contaminants in the air.
"Zhu and her colleagues have been collecting samples of wildfire smoke in neighborhoods near the fires. It’ll be months before that data is fully analyzed, but Zhu suspects she will find a dangerous mix of chemicals, including, potentially, #asbestos and lead — materials used in many buildings constructed before the 1970s.
"The risk will linger even after the smoke clears. The plumes that wafted over the landscape will deposit chemicals into drinking #water supplies and #contaminate# soil. When rains do come, they’ll wash #ToxicAsh into streams and across the land, said Fernando Rosario-Ortiz, an environmental engineer and interim dean of the University of Colorado Boulder environmental engineering program. 'There’s a lot of manmade materials that are now being combusted. The potential is there for contamination,' he said, noting that little research on how toxic ash and other byproducts of wildfires in urban areas currently exists. 'What we don’t have a lot of information on is what happens now.'
"After the Camp Fire razed Paradise, California, in 2018, water utilities found high levels of volatile organic compounds [#VOCs] in #DrinkingWater. Similar issues have arisen in places like Boulder County, Colorado, where the Marshall Fire destroyed nearly 1,000 structures in 2021, Rosario-Ortiz said, though the presence of a contaminant in a home doesn’t necessarily mean it will be present in high levels in the water. Still, several municipal water agencies in Los Angeles issued preemptive advisories urging residents not to drink tap water in neighborhoods near the Palisades and Eaton fires. It’ll be weeks before they know exactly what’s in the water.
"As wildfires grow ever more intense and encroach upon urban areas, cities and counties must be prepared to monitor the health impacts and respond to them. 'This is the first time I’ve ever even witnessed or heard anything like this,' said Zhu, who raised her daughter in Los Angeles and has lived there for decades, said. 'Even being in the field studying wildfires and air quality impacts, I never imagined that a whole neighborhood, a whole community in Palisades, would burn down.'"

Me: Hey look, there is an #aqi station nearby! I wonder if I can get it in #homeassistant
(Insert a montage, but not a good one because the "real" #airquality integration is abandoned and poor but ♥️ #oss for a working fork)
Also me: Well fuck you too #CanadianHaze. I wanted to swim today. -
I have a Bosch #BME680 at an #ESP 8266 outside that offers Air Quality Monitoring - #AQI.
They reach values of >200 with lowest values i have see after rain being down to 80.
The internet claims values over 200 are really bad - anyone any experience with those sensors outside? What does your sensors show? #AitQuality #AirQualityMonitoring #Rotterdam
