NYU FloodSense street sign mounted flood depth sensor

Water depth level 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 traffic, as well as depositing micro-organisms on the street. Ultrasonic technology is used to detect flood water depth.

The sensor transmits its data via LoRaWAN and is equipped with a solar panel for continuous operation.

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

Two flood events have been observed in this dataset between these date ranges:

1. "2020-11-15 19:37:00.000000000-05:00" to "2020-11-16 00:30:00.000000000-05:00"

2. "2020-11-30 10:20:00.000000000-05:00" to "2020-11-30 13:30:00.000000000-05:00"

Erroneous data has been observed:

• There are ~1% decreases in depth measures on days with sun which suggests that the distance sensor is affected by direct sunlight

This data is preliminary and is for prototyping purposes. 

This dataset will be updated when more data is collected.
