Short summary
Our yearlong study examined the performance of low-cost sensors for monitoring ozone and fine particulate matter. They benefit from regular, in-season adjustments – monthly recalibration proved most effective – to deliver reliable data. Using an uncommon recalibration method and state-of-the-art air sensor test protocols for evaluation, we showed the importance of recurrent calibration to maximize sensor performance and to broaden their scope of application, particularly for ozone monitoring.
