This repository houses information regarding the build, deployment, and maintenance of the FloodnNet project's flood sensor.
FloodNet is a partnership between academic researchers at New York University and the City University of New York, and NYC municipal agencies (NYC Mayor’s Office of Climate & Environmental Justice and Mayor’s Office of the Chief Technology Officer), working in consultation with community organizations.
note: This repository is relevant only to the flood sensors, i.e., the end-device sensing component within a larger sensor network infrastructure. For more details about the complete network infrastructure(figure below) refer to the FloodNet documentation website.
Further, Gateway and NodeRED repositiories are linked in the additional resources section for reference.
This section contains the necessary resources to build a flood sensor from the raw materials state to a final product.
The FloodNet's flood sensors are deployed on street sign posts, over the sidewalk, following the permission from NYC to do so. This section details instructions to identify a deployment location, choosing an optimal mounting option, and finally, deploying a flood sensor.
The sensor is susceptable to noise in the following scenarios - mounted over grass, mounted over soil/bumpy sidewalk, and when sensor measuring area is of different heights for example is half sidewalk and half road.
Sensor can be mounted in two ways: on the front side, and on the back side of the drive rail.
Back Side: If mounting on the back side (figure below), the mount needs to be wider and in this case use a Slotted Flat Mending Plate and 4" hex bolts for mounting the whole assembly onto the drive rail.
Front side: When mounting on the front side, the L-bracket can be direclty mounted onto the drive rail like shown below.
Align the sensor horizontal to the ground, while avoiding too much tilt on any sides.
Solar panel mount: Mount the panel on the top of the struct channel mount with the panel facing the South direction.
Bundle the solar cable and ziptie it to secure it beneath the struct chanel and away from the sensor cone.
The maintenance maual is the README.md document which contains the information needed for sensor maintenance runs and visits. Below are a list of common maintenance visit reasons listed and linked to the recommended fixes detailed on the manual.
