Environmental sensors contribute to smart city initiatives by providing real-time data on air quality, temperature, and noise levels, among other factors. This data helps city planners and officials make informed decisions that enhance the quality of urban life. With the integration of these sensors into the city's infrastructure, municipalities can monitor environmental conditions, respond to issues promptly, and implement policies that promote sustainability. Additionally, this technology can engage citizens, as real-time data sharing fosters transparency and encourages public participation in environmental stewardship efforts.
