NASA says 2.1MM deaths annually due to PM2.5 pollution.
[A version of this was original posted on our Facebook feed]. “2.1 million deaths occur worldwide each year as a direct result of a toxic type of outdoor air pollution known as fine particulate matter (PM2.5)” according to Environmental Research Letters study cited in a NASA article. (This is, of course, the type of dust pollution that our app lets take control of, especially in your home.) If you live in a major city anywhere in the world, you need to be concerned about premature death due to PM2.5 particulate dust, with the possible exception of people living in Florida (!). (The article actually compares current dust pollution levels to pre-industrial pollution levels.) China and India are, of course, off the scale, a concern for neighboring countries like Japan, South Korea, and the West Coast of the U.S. that get airflows from their cities. [We’ve noticed that air pollution in Los Angeles seems much worse in the winter than in the summer.… Read the restHome Automation and the Internet of Things; answers to readers comments
CES blog posts Our CES reports on new robotic vacuum cleaners, smart refrigerators, and environment-sensing scales were some of our most popular posts with our readers, as was our coverage of Cisco’s talks on the Internet of Things. There’ll probably be a few more CES reports to share. In future posts, we’re going to cover some of the new home automation gadgets coming out that will make the Internet of Things a reality. Trouble is, too many existing appliances weren’t designed to network. Let’s say you wanted to use our app to decide when to turn your gas dryer, fireplace, or furnace on or off based on airborne combustion levels. That’s hard to do right now. Home Automation and the Internet of Things But a number of small startups are tackling this problem with innovative gadgets that interact with legacy electric appliances like washing machines and dryers. Some feature cameras, optical sensors, outlet switches, and mechanical activators together with a WiFi connection and logic that’s designed to make it easier to let the dryer signal you (over the Internet) when it’s done or even let you control the dryer from a website.… Read the restBad air pollution day in your city? Here’s the tech to get.
Sensor and purifier recommendations for a bad air day Saturday (Jan 4, 2014) we knew something was wrong in Los Angeles. Like any tech startup, we were in the office working, when our indoor dust sensor (& this less expensive version that we also support) started showing PM2.5 air pollution particle counts off the scale without any good (indoor) reason for the air being that bad. This despite our highly-regarded heavy-duty air purifier being on the maximum “Turbo” setting. PM2.5 dust levels to remember Since we weren’t running any indoor polluters (like a dishwasher or gas appliance), bad outdoor air could be the only reason. Sure enough, we checked with our iOS app. Los Angeles air was in the orange “Unhealthy for Sensitive Groups” some of the worst air quality we’ve ever seen with our app in Los Angeles. (We did see the air quality in San Jose deteriorate all the way into the brown or “Unhealthy” region right before Thanksgiving, maybe because of the all the cars and airplanes accommodating travelers.… Read the restRecent Comments
