Objects commonly situated in the environment can be used to gather a variety of information about the environment proximate to the respective objects. For example, smart manholes (e.g., manholes configured with sensors and communications devices) or smart manhole covers can include a suite of sensors that can detect various states or events including air pollutants, earthquakes, flooding, gas leaks, sewage, environmental contamination, ultraviolet levels. Furthermore, smart manholes or smart manhole covers can be used to communicate with other devices and perform more complex operations including traffic monitoring.
