‘Look’ you breath with new air quality monitoring
#Cosmoread: People generally think about clean or dirty air only when they’re out, but the indoor air quality can be a significant problem. Some smaller than the width of a hair – – and now, using a new gadget, people can identify pollutants in their homes, and it can help ward off certain diseases, said the creators of the device.
AirVisual – scientists, engineers and others a global team – Gadget, AirVisual called node is producing. Bright and colorful screen node pollution, temperature, moisture and humidity can illuminate both inside and out. The team approach to air quality is expected to replace the collection, Yan Boquillod, AirVisual co-founder said.
People generally do what they are breathing on the street, because most governments have some understanding of actively monitoring wind, Boquillod said. Indoor air, on the other hand, a “great unknown,” he told Live Science. “80 to 90 percent of their time indoors, you have to spend, so if you really control your indoor air quality are capable of,” so you can protect your family’s health If, Boquillod said.
Using this monitor, “I have my children are breathing much pollution is visibility,” he said.
Indoor air pollution
Indoor air pollution, stove tops, fireplaces and wood products, among other sources can come from the US Environmental Protection Agency (EPA) states. Food, water, in particular, can be released into the air contaminant-laden smoke, Boquillod said. Node these contaminants, the microscopic particles, or particulate matter is called, PM2.5 can include can identify. “2.5” particles, which comes from a diameter of 2.5 micrometers. “It’s a very small particles, is much smaller than a hair,” Boquillod said.
Node 10 micrometers in diameter (PM10) can measure the particles, including dust. Tiny PM10 particles can be inhaled in
to the lungs and get past the body’s normal defense system, eventually enter the bloodstream, Boquillod said. The eyes, nose and throat irritation that can lead to health issues like, he said. Small particles deep into the lungs, can nail, respiratory infections, bronchitis and even cause lung cancer, EPA accordingly.
Node capable of measuring particles using laser technology, the company said. Inside the nodes, there is a fan that sucks in ambient air, a laser that shoots a fast and precise laser beam, and the laser is a photo-sensor. “Whenever particulate matter passes in front of the photo-sensors, it breaks the laser beam,”
Intervention by the photo sensor is raised, the Boquillod said. “The photo-sensor counts how many times the laser beam is broken.”
The device has a powerful algorithm that identifies the size and number of particles for each intake and overall air pollution extrapolates the data to determine the intake depends on continuously, Boquillod said. In addition to examining the particles, the device also has carbon dioxide levels, which can indicate that measures how well a room is ventilated. Large amounts of carbon dioxide are concentrated, stuffier gets a room.
Carbon dioxide levels get too high, “you feel like you are most of our cognitive power,” Boquillod said. 10,000 ppm node per million (ppm) carbon dioxide concentrations of 400 parts can measure. 1,000 ppm of carbon dioxide is reached, the environment is limited and need some fresh air, and when the level rises to 1,500 ppm, people will start to feel bad, he said. 2,000 ppm level soars, it’s time to get out and airy, Boquillod said.
The best place to collect air quality data that you spend the most time, Boquillod said, which may be in the bedroom or living room. Node, on the road to measure air pollution, the device needs to be in the shade can be used off the air and shielded from the rain. A node connected to the Internet AirVisual, which strengthen and worldwide data is planning to share can send outdoor air quality measurements.
The nodes, crowdsourcing site Indiegogo are sold on the revenue generated by worldwide AirVisual to map air pollution will help fund social projects. However, governments in a number of countries already collect air quality data, many other countries are poorly monitored, compromise the health of the citizens in those places, Boquillod said.
AirVisual currently part of an app and a website that provides forecasts and global air quality. The group as a non-governmental organization has the same goal, but in the distribution of self-financing to increase its capacity to collect data and wants to be, Boquillod said.
AirVisual node sells for $ 149 and $ 25,500 on Indiegogo, or 255 percent of its initial $ 10,000 goal, is collected. Crowdfunding 18 days left in the campaign, and is planning to gadget Airvisual team in April, Boquillod said.
