This sensor will be very important for cities with industrial sector
Bengaluru Scientists from the Center for Nano and Soft Matter Sciences (Cens), an autonomous institution of the Department of Science and Technology (DSS), have prepared a special sensor, which can detect the toxic elements in the air. This sensor is completely new and its cost is also very low. These sensors can help detect toxic sulfur dioxide (SO2) gas responsible for excessive low concentrations, respiratory irritation, asthma seizures and long -term lung damage.
Sulfur dioxide may cause serious health problems
Sulfur dioxide (SO2) is a poisonous air pollutant that usually comes out of trains and industrial emissions. Its minor contact can also cause serious health problems and lung damage to the lungs long term. It is difficult to detect before it affects health. It is important to monitor the level of SO2 in real time for public safety and environmental protection. Existing techniques are often expensive, energy-intensive, or unable to detect gas at trace levels.
Sensor prepared from nickel oxide and neodium nickel
Bangalore scientists have prepared this sensor by mixing two metal oxide (NIO) and Neodium Nicel (NDNIO 3) through a simple synthesis process to overcome this. Nickel acts as a receptor for oxide gas and acts as a neodium nickel transducer, which transmits the signal efficiently. This makes it possible to detect as low concentrations as 320 PPB, which exceeds the sensitivity of many commercial sensors.
Dr. S. Angappan -led team developed prototype
To showcase the capabilities of this sensor, Dr. S. The team led by Angappan developed a portable prototype, which includes sensors for monitoring SO2 in real time. The prototype has a straight-based border-based warning system, which activates green for safe, yellow for warning and red visual indicators for danger. With this, users can easily interpret and react without scientific expertise.
Extremely important for cities with industrial sector
Its compact and light design makes it suitable for use in industrial areas, urban places and attached places, where continuous air quality monitoring is necessary. With its high sensitivity, portability and user friendly operations, these sensor systems provide a practical solution for monitoring and management of SO2 pollution, supporting public health and environmental protection. This work displays the ability of physics to create accessible techniques for real -world challenges.
Which more role in making sensors
Vishnu ji Nath has designed this sensor. In this, Dr. Shalini Tomar, Mr. Nikhil N. Rao, Dr. Muhammad Safir Naduvil Kovilkath, Dr. Nina S. John, Dr. Satdeep Bhattacharya and Prof. Soung-Chaol Lee also contributes. This research is published in a journal called Small.
