NEW DELHI: Researchers at the Indian Institute of Technology, Kharagpur, have developed a low-cost dirt detector that promises to take the sweat out of cleaning.
The smart hygiene monitor (SHM) records levels of ammonia, sulphur dioxide, carbon monoxide, carbon dioxide, volatile organic compounds and particulate matter through sensors and sends online alerts to stakeholders when a certain threshold is crossed. It can be installed at any place where cleanliness needs to be monitoredat regular intervals.
At present, public facilities such as toilets, eateries, hospitals, parks, airports and railway stations are generally cleaned at fixed intervals, irrespective of how dirty they are.
Aurobinda Routray, who headed the team at the institute’s electrical engineering department which created the device, said the device can help reduce use of water, harmful cleaning agents and even manpower by alerting authorities to the need to clean an area only when needed. read more...
