Beijing-based healthcare firm Kaiterra, on Monday launched Laser Egg+ CO2 air quality monitor in India for Rs 16,995.
This is the first indoor air quality monitor for homes from Kaiterra to measure CO2, in addition to four other key pollutant indicators – PM2.5, air quality index, temperature and humidity.
“The addition of the Laser Egg+ CO2 to our dynamic product portfolio brings CO2 monitoring to consumers’ fingertips. Most consumers do not realise that moderate levels of CO2 commonly found in their home can lead to a cumulative negative impact on health and wellbeing,” Liam Bates, CEO and Co-founder of Kaiterra said in a statement.
The Laser Egg+ CO2 is powered by sensors and a cloud-based calibration which aims to provide accurate, real-time readings from reference-grade monitors stationed across the globe.
Like its predecessors, Laser Egg+ CO2 can be monitored from a mobile device via the Kaiterra App. The app provides consumers with access to trends and real-time monitoring, as well as the ability to set alerts when air exceeds the pre-selected level. (IANS)
Sydney: Researchers are developing a laser system for a non-invasive, on-site breath analysis that can screen various diseases including diabetes, infections and cancer in a moment.
The team from University of Adelaide has developed an instrument like an “optical dog’s nose” that uses a special laser to measure the molecular content of a sample of gas, which can hit the market in three-five years.
“The laser system uses light to ‘sense’ the range of molecules that are present in the sample,” said James Anstie, research fellow with the university’s Institute for Photonics and Advanced Sensing (IPAS).
Those molecules are by-products of metabolic processes in the body and their levels change when things go wrong.
Diseases like lung and esophageal cancer, asthma and diabetes can be detected in this way even before external symptoms are showing, said the study that appeared in the journal Optics Express.
The system uses a specialised laser that sends up to a million different light frequencies through the sample.
Each molecule absorbs light at different optical frequencies and, therefore, has a unique molecular fingerprint.
“The next step is to work out how to accurately sample and interpret the levels which will naturally vary from person to person,” the researchers said.
Other potential applications include measuring trace gasses, such as atmospheric carbon dioxide, and detecting impurities in natural gas streams.

Online Social networking Service Provider, Facebook has been working on ways to beam internet to people from the sky. There would soon be huge solar-powered drones – with the wingspan of a commercial airliner— beaming down internet in the remotest of areas.
Facebook has been testing such drones in the skies over England, according to its CEO Mark Zuckerberg. The drones use lasers to beam internet access down to the ground, designed to provide connections to rural and internet-free zones.
“As part of our Internet.org effort to connect the world, we’ve designed unmanned aircraft that can beam internet access down to people from the sky,” Zuckerberg said in a blog post.
“We’ve successfully completed our first test flight of these aircraft in Britain,” he wrote.
Developed by Ascenta, a Somerset-based designer of solar-powered drones bought by Facebook in March 2014, the drones will be able to fly at altitudes of 60,000 feet for months at a time on solar power. They will have wingspans greater than 29 metres, or that of a Boeing 737, but weigh less than a car.
“Aircraft like these will help connect the whole world because they can affordably serve the 10 percent of the world’s population that live in remote communities without existing internet infrastructure,” Zuckerberg said.
The drones form part of Facebook’s internet.org initiative that aims to connect the next billion people to the internet, creating new markets for the social network which already connects 1.39 billion monthly active users.
“If we achieve our first goal, get everyone on the internet, build services at scale for the entire planet, we create this new problem: so much information you can’t consume the stuff that’s important to you,” Facebook’s chief technology officer Mike Schroepfer was reported as saying.
“We’ve made good progress so far. Over the past year, our work in the Philippines and Paraguay alone has doubled the number of people using mobile data with the operators we’ve partnered with, helping 3 million new people access the internet.” Zuckerberg elaborated.
Meanwhile, Google is reported to be planning to provide internet access to non-connected areas using both high altitude balloons and drones, buying American drone firm Titan Aerospace in April last year.
“We’re going to continue building these partnerships, but connecting the whole world will require inventing new technology too. That’s what our Connectivity Lab focuses on, and there’s a lot more exciting work to do here.” said Zuckerberg talking about his future plans.
Facebook had over 1.3 billion active users as of June 2014.
