Twenty low-cost sensors developed by indigenous start-ups have proven accuracy of round 85-90 per cent in comparison with regulatory grade screens throughout a seven-month pilot venture performed in partnership by Maharashtra Pollution Control Board (MPCB). Indian Institute of Technology, Kanpur (IIT-Ok) and Bloomberg Philanthropy.
These have been amongst a fleet of 40 low-cost sensors developed and deployed for the research by 4 totally different start-ups. The findings confirmed that the sensors on the three start-ups noticed a one p.c error – measured in relation to the true worth measured by the Continuous Ambient Air Quality Monitoring Station – for lower than 25 p.c for uncalibrated values. After calibration, the error was decreased to lower than 15 p.c for 3 varieties of sensors and fewer than 20 p.c for the fourth kind.
The research was performed between November 2020 and May 2021, when MPCB’s 15 current real-time ambient air high quality monitoring stations or CAAQMS in Mumbai in addition to 40 much less at Colaba, Worli, Sion, Bandra, Vile Parle, Kurla Cost monitoring sensors have been put in. International Airport, Powai, Kandivali, Mulund, Borivali, Vasai, Mahape, Nerul, Kalyan.
Dr VM Motghare, Joint Director (Air Quality), Maharashtra Pollution Control Board mentioned, “We (Maharashtra) have the best variety of non-attainment cities and there’s a want for macro planning to observe the implementation of the National Clean Air Programme. So, the info from these low-cost sensors will truly assist us determine hotspots within the state.”
