According to the WHO, 90 percent of the world’s population lives in a place where they are exposed to unsafe levels of airborne pollutants, contributing to up to seven million deaths each year. If you live in a city, chances are that you’re part of that 90 percent, even if your city is relatively clean. That’s why cities worldwide have started embracing Internet of Things (IoT)solutions.
One of the best ways to fight pollution is to figure out where it’s worst and where it’s coming from. If you’ve ever made a habit of checking air quality around you, you may notice that there aren’t actually that many monitoring stations, and your closest one may not be that close. For pollution data to really be accurate and helpful, we need a lot more of it.
Luckily, IoT sensors and low-power wide-area networks are making it a lot easier to get and spread ultra-local data. Lampposts are one popular place to put them. For example, the Republic of Korea and Barcelona have already built out a network of pollution sensors in their streetlights. On the other hand, outfitting (配备) cars, bikes, and even people with pollution sensors provides valuable data on a smaller, more mobile scale.
Since pollutant levels can change dramatically even from one city block to another, having smaller-scale data is important for making a lot of decisions that, over time, might have a major influence on our health and behavior. It can influence where we decide to live, when we exercise, whether we bike to work, and, perhaps most importantly, what we can do about pollution in our area.
What all the Internet of Things can help us do on a personal level is use less energy. The data it provides, though, can be used to make big and small changes to the way we behave and build, and that is eventually where we’ll see benefits.

Ali Coletta always wanted someone to share her adventures. Then she met her husband Nick, and things seemed perfect — for a while. But she knew there was still something, or someone, missing.
“I knew we needed an addition to our family to share our passion for adventure together,”Ali said.“I even created a PowerPoint slideshow on why we needed a sweet golden retriever (金毛猎犬) in our lives.”
In 2016, Stella joined the family and the Colettas finally found the perfect pet to make them feel complete.“Stella’s personality is lovely and contradictory. One minute she’s sitting at the kitchen table as if it’s no big deal, and the next minute she’s bossing us around,”Ali said.“She loves swimming, hiking and recently snowboarding.”
The fearless pup loves following Nick around wherever he goes and is always up for an adventure. This was never more apparent than when the family went on a recent ski trip. Their vacation was cut short due to COVID-19, but on their last day, the family hiked up a mountain park. Of course, they brought Stella along for the journey so she, too, could enjoy the snow. Then something unexpected happened — as Nick began snowboarding downhill, the faithful Stella refused to be left behind. She bounded happily through the snow, following Nick’s every move. “We knew she would love the hike in the snow,” Ali said.“But we honestly had no idea she would love running down just as much.”
Stella has always loved the cold, and now it’s clear that she’s finally found her calling.
Regardless of what Stella does, the Colettas couldn’t be happier to have such a special pup in their lives. “She truly completes our family and is the best companion one could ask for,” Ali said.
