Study Finds Calibration Essential for Reliable Low-Cost Air Quality Sensors in India

A study by Bengaluru-based CSTEP evaluated 48 low-cost air quality sensors from six manufacturers over up to eight months, finding significant variability in pollutant readings and reliability issues. Sensors often gave inconsistent or faulty data unless calibrated for local conditions, such as Bengaluru's environment. Calibration improved sensor performance, highlighting the need for location-specific adjustments to ensure accurate and durable air quality monitoring in developing countries like India.
