An MPCB-IITKanpur-Bloomberg study has revealed that new low cost pollution or air quality sensors are showing an efficacy of 85% over earlier monitors. MPCB and other experts recommend it could be a good option to make the Mumbai region’s monitoring Network<\/a> more dense and sensitive to pollution by monitoring additional hotspots. The move, they say, may help the administration take immediate corrective actions to keep air clean.<\/p>\n

Twenty low-cost sensors developed by indigenous start-ups have shown an accuracy of nearly 85-90% vis–vis regulatory grade monitors during a seven-month pilot project conducted by the Maharashtra Pollution Control Board (MPCB) in PARTNERSHIP<\/a> with Indian Institute of Technology<\/a>, Kanpur (IIT-K) and Bloomberg Philanthropies.<\/p>\n

These were among a fleet of 40 low-cost sensors developed by four different start-ups and deployed for the study. The findings reveal that sensors from three start-ups saw a Percentage<\/a> error (measured with respect to true value measured by CAAQMS) of less than 25% for uncalibrated values. After calibration the error was reduced to less than 15% for three types of sensors and 20% for the fourth type.<\/p>\n

The study was conducted between November 2020 and May 2021 when 40 low-cost monitoring sensors were installed alongside MPCBs 15 existing continuous (real-time) ambient air quality monitoring stations (CAAQMS) – Colaba, Worli, Sion, Bandra, Vile Parle, Kurla, International Airport, Powai, Kandivali, Mulund, Borivali, Vasai, Mahape, Nerul, Kalyan.<\/p>\n

The findings of the study have thrown open the possibility of expanding not only Mumbai region but the countrys monitoring network at a fraction of the cost. While regulatory grade monitors could cost upward of Rs 20 lakhs, the start-up built small sensors cost around Rs 60,000.<\/p>\n","protected":false},"excerpt":{"rendered":"
