NYU FloodSense Gowanus Canal mounted distance sensor

Ultrasonic distance data in mm from a sensor mounted above the Gowanus Canal, Brooklyn, NY (40.674490, -73.994458). The sensor is designed to detect flood water that fills the street and blocks vehicle and pedestrian traffic, as well as depositing micro-organisms on the street. This one is used for data validation. The sensor transmits its data via LoRaWAN and is equipped with a solar panel for continuous operation. Data is collected at ~5min intervals. Time fields are in local time (New York). One type of erroneous data has been observed: There are ~1% rises in distance measures on days with sun which suggests that the distance sensor is affected by direct sunlight This data is prelimary and is for prototyping purposes. Not to be used as a reliable data source as it is. This dataset will be updated when more data is collected.
