Regular checks key to improving low-cost air quality sensor efficiency: Study

While low-cost air quality sensors offer an affordable and promising way to expand pollution monitoring in countries of the Global South, such as India, their readings could vary widely unless properly calibrated for local conditions, shows a study by Bengaluru-based Center for Study of Science, Technology and Policy’s (CSTEP).

Titled Performance Evaluation of Multi-pollutant Air Quality Sensors at Indi-SET, Bengaluru, India – First Edition; A Short- and Medium-Term Evaluation, the report emphasises that the effectiveness of such sensors depends on regular evaluation.
