The integration of technology into urban infrastructure has reached park furniture, with innovative smart benches now capable of monitoring various environmental factors. While traditional park chairs serve basic seating purposes, advanced models equipped with multi-sensor systems can indeed detect and measure deodorizer pollution alongside other air quality parameters. These sophisticated benches incorporate chemical sensors specifically calibrated to identify volatile organic compounds (VOCs) commonly found in artificial deodorizers and air fresheners.

The detection mechanism operates through built-in gas sensors that measure particulate matter and chemical composition in the immediate surroundings. When deodorizer particles or other pollutants are present, the sensors trigger data collection processes that analyze concentration levels. This information is then processed through onboard algorithms that distinguish between different types of airborne substances, including those originating from personal care products, cleaning agents, or environmental pollutants.

These smart benches typically form part of larger urban IoT networks, transmitting real-time air quality data to central monitoring systems. Municipalities and environmental agencies utilize this data to identify pollution patterns, monitor public space air quality, and implement targeted improvements. The technology represents a significant advancement in urban planning, transforming passive street furniture into active environmental monitoring stations.

While not yet universally implemented, several smart city initiatives across Europe and Asia have successfully deployed these advanced benches. The data collected helps cities understand how personal care product usage in public spaces contributes to overall air quality, enabling more informed decisions about urban environmental management and public health initiatives.
