Out of sight means out of mind? Not necessarily.
Small airborne particles may not be visible to our naked eyes, but they have us worried all the time. We fret about the dust around us as it can severely affect our health and cause a series of ailments starting from asthma and bronchitis to lung cancer.
But now, one can actually know how high is the pollution level in a given environment and the chances of falling ill, thanks to a dust sensor developed by a Sindri boy.
Twenty two-year-old Ankush Kumar’s device called Blue Monitor can detect the dust level in any environment — be it home, hospital, hotel or industrial unit. Equipped with a sensor and microprocessor, the portable device has a display screen, which indicates different level of cleanliness.
Kumar, who is currently pursuing BTech in electrical and electronics engineering from Motihari College of Engineering in Bihar, has recently applied for the patent of his invention. “The sensor sends the data to the microprocessor, which after analysing it, indicates the pollution level on a scale of 1 to 9,” Kumar said.
When Blue Monitor is installed in any environment, it conducts a routine check of the surroundings and begins to provide data within minutes. Numbers are then displayed on the screen. If the number is less then 1, it shows letter “C”, which implies that the particular room is dust-free, Kumar explained.
If the number is greater then 9, it will show letter “A”, indicating that the room is highly polluted and needs immediate cleaning, Kumar added.
“I have already carried out successful demonstration of the machine at separate workshops in DAV High School, Tasra, in February 2013 and Rajkamal Saraswati Vidya Mandir in Dhanbad in October 2012,” Kumar said.
Blue Monitor has also bagged the first prize in the embedded system category of a contest organised by IIT-Delhi’s Robotics organisation Reg’52 last year. Since the device requires only DC voltage, its electrical consumption is low. It can also run on battery.
The device costs a mere Rs 1,500. “The price can further reduce to around Rs 300-400 if a cheaper version of the microprocessor is used,” Kumar added.
The third year engineering student’s website www.toothless.in has the detailed description of Blue Monitor.
