In the era of smart cities, innovation extends to public furniture like park benches. Recent advancements have led to the development of smart benches equipped with environmental sensors capable of detecting various pollutants, including smoke pollution. These benches integrate IoT technology to monitor air quality in real-time, measuring particulate matter (PM2.5 and PM10), carbon monoxide, and other harmful emissions from sources like wildfires, industrial activities, or vehicular exhaust.

The sensors embedded in these benches collect data and transmit it wirelessly to centralized systems, providing valuable insights for urban planners and environmental agencies. This technology not only helps in tracking pollution levels but also raises public awareness through digital displays or mobile app integrations, alerting park visitors to current air conditions.

While not yet ubiquitous, pilot projects in cities like Singapore and London have demonstrated their effectiveness. Such initiatives represent a growing trend toward leveraging everyday infrastructure for environmental monitoring, contributing to healthier urban spaces. However, challenges like cost, maintenance, and data privacy remain considerations for widespread adoption. Ultimately, these smart benches symbolize a fusion of functionality and sustainability, redefining how public spaces can serve dual purposes of leisure and health protection.
