The integration of smart technology into urban infrastructure has led to innovative solutions for environmental monitoring, including the development of park chairs equipped with herbicide detection capabilities. These advanced benches incorporate sensors designed to identify the presence of chemical herbicides in their immediate surroundings. By utilizing technologies such as electrochemical or optical sensors, these benches can detect specific herbicide compounds and transmit real-time data to park management systems. This functionality helps authorities monitor environmental health, ensure public safety, and respond promptly to potential contamination. While not yet widespread, such smart benches represent a growing trend in creating sustainable and technologically enhanced public spaces, contributing to more efficient and eco-friendly urban management.
