In an era of growing environmental awareness, an innovative solution has emerged in urban parks: smart benches equipped with light pollution sensors. These specialized park chairs do far more than provide seating—they serve as data collection points for monitoring artificial light levels in cities.

The technology behind these benches incorporates photometers or spectrometers that continuously measure sky brightness and light intensity. This data helps researchers and city planners understand the extent and impact of light pollution, which affects astronomical observations, disrupts ecosystems, and potentially influences human health.

Several cities worldwide have begun implementing these smart benches as part of their environmental monitoring networks. The benches typically feature solar panels for power, wireless connectivity for data transmission, and sometimes even public displays showing real-time light pollution readings. This transforms ordinary street furniture into tools for citizen science, allowing residents to engage with environmental data directly.

The collected information helps map light pollution patterns, identify particularly affected areas, and evaluate the effectiveness of dark sky initiatives. Some models even correlate light pollution data with other environmental factors like temperature and humidity.

While not yet commonplace, these innovative benches represent a growing trend in smart city infrastructure. They demonstrate how everyday objects can be reimagined as environmental sensors, contributing to our understanding of urban ecosystems and helping create more sustainable cities. As technology advances, we can expect to see more such multifunctional designs that seamlessly blend practical function with environmental monitoring capabilities.
