The sensor will measure the level of harmful gases, including ozone and nitrogen oxides, said professor S N Tirpathi.
Testing of the sensor will be done in June and if it passes the test, then the sensors will be installed in 150 cities of the country, he told reporters during a press conference on Wednesday.
After the testing of data, 50-60 sensors will be installed in Varanasi, Tripathi said.
He said the success was gained in developing a reliable and cheaper monitoring sensor under a India-US project.
The Union government's Department of Science and Technology has contributed Rs 6 crore for the project, Tripathi said.
"So everyone has decided that they will work together to decrease pollution," he added.
Quoting a report of the WHO, he said 1.60 lakh people died worldwide last year due to pollution and the death rate is increasing.
He said former students of the institute living in these countries will work on the project.
