The integration of smart technology into urban furniture has led to innovative designs, including park chairs with built-in pH sensors. These advanced benches are designed to monitor soil or water pH levels in real-time, providing valuable data for environmental maintenance while offering comfortable seating.

While not yet widespread, prototypes and pilot projects have demonstrated their feasibility. Such chairs often use durable, weather-resistant materials and low-power sensors connected to IoT networks. They represent a fusion of sustainability and functionality, appealing to eco-conscious cities.

The primary challenges include cost, durability, and data accuracy in outdoor conditions. However, as smart city initiatives grow, pH-sensing park chairs could become valuable tools for environmental monitoring in public spaces. Current models typically feature solar-powered systems and discreet sensor placement to maintain aesthetic appeal.

This emerging technology highlights how everyday urban furniture can serve dual purposes—enhancing public comfort while contributing to environmental stewardship through innovative sensor applications.
