Air is drawn into the device, and an LED shines a light on the sample. Because they’re so small, they can get deep into our lungs and cause acute effects, like asthma attacks, as well as chronic effects like lung cancer.ĪirBeam uses a light-scattering method to detect particles. These particles are created by diesel cars and trucks, coal-burning power plants, and forest fires, among other sources. There are a number of factors that impact air quality, and AirBeam focuses on one that is especially prevalent in cities: tiny particulates less than 30 microns in size - 30 times smaller than the width of a human hair. With AirBeam, a wireless air quality monitor now on Kickstarter, they’re hoping that a distributed network of “aircasters” will be the next big citizen science initiative. The folks at Brooklyn-based nonprofit HabitatMap make it their goal to spread awareness of the connection between the environment and human health. Via: ElComercio.pe Image Source: ElComercio.pe & Twitter It will be impressive to watch what is next for this 14 year old and the next generation of kids as they continue to experiment with open hardware and all of the new data and platforms available to them in the years to come. You can improve time and efficiency by adding more sensors in Chile, which will happen” So far it has detected all the earthquakes that people feel (about 5 degrees Richter more or less) with five to 20 seconds in advance, depending on the distance from the hypocenter.
When asked about the success of his current setup he answered ” I predicted five earthquakes since April. According to El Comercio others have already contacted him to spread the system in other parts of the country as the Chilean government's online warning system is not fully operational. Sebastian is currently working with local cell phone providers to try and hook his system up to SMS alerts which would result in up to a minute of advanced warning time. The result? Now the 77,000+ followers on his are given an extra 5-20 seconds to prepare themselves when the next big one hits. Sebastian pulled this detector apart and replaced the internal circuit with an Arduino board, connecting this newly outfitted device to his server and eventually online through the Twitter API. Sebastian began his project with the purchase of an off-the-shelf “P” wave (compression wave) QuakeAlarm detector for $75 which provides some added warning time in the case of an emergency through an audible alarm system. Sebastian Alegria is a 14 year from Chile who has hacked together a Twitter based regional earthquake alert system after seeing his country experience a magnitude 8.8 earthquake in 2010 (Largest quake ever was also recorded in Chile in 1960) and learning about the lives saved in Japan’s 2011 quake from the advanced early warning system operated there.
