NYU FloodSense street sign mounted flood depth sensor

<p>Water depth level&nbsp;in mm from a sensor mounted on a street sign post at the corner of 5th Street and Hoyt, Brooklyn, NY (40.676640, -73.994595). The sensor is designed to detect flood water that fills the street and blocks vehicle and pedestrian&nbsp;traffic, as well as depositing micro-organisms on the street. Ultrasonic technology is used to detect flood water depth.</p> <p>The sensor transmits its data via LoRaWAN and is equipped with a solar panel for continuous operation.</p> <p>Depth data is collected at ~5min intervals. Time fields are in local time (New York). Date format is: 2020-10-04 20:11:45.742594232-04:00</p> <p>Two flood events have been observed in this dataset between these date ranges:</p> <ol> <li> <p>&quot;2020-11-15 19:37:00.000000000-05:00&quot; to &quot;2020-11-16 00:30:00.000000000-05:00&quot;</p> </li> <li> <p>&quot;2020-11-30 10:20:00.000000000-05:00&quot; to &quot;2020-11-30 13:30:00.000000000-05:00&quot;</p> </li> </ol> <p>Erroneous data has been observed:</p> <ul> <li>There are ~1% decreases&nbsp;in depth measures on days with sun which suggests that the&nbsp;distance sensor is affected by direct sunlight</li> </ul> <p>This data is preliminary and is for prototyping purposes.&nbsp;</p> <p>This dataset will be updated when more data is collected.</p> <p>Please see our github org for sensor information and build instructions:&nbsp;<a href="https://github.com/floodsense">github.com/floodsense</a></p>
