The Project

We have been funded by the National Science Foundation for development and testing of custom, inexpensive, multi-parameter dataloggers with integrated RF telemetry capability to allow for wireless streaming of data from sensor mininodes to an internet-connected base node. This is a continuation of our recent work on cabled, networked, nearshore observatories.

We have partnered with long-time collaborator, Paepae o He`eia, to implement this wireless coastal sensor network in the He`eia ahupua`a (watershed) to assist with environmental restoration and management efforts and engage K-12 and undergrad audiences in STEM training.

The spaces, links, and datasets provided here are rapidly evolving and largely preliminary. Please contact Brian Glazer with any project related questions, or Stanley Lio for questions regarding data access, system design and implementation.

Wireless sensor mininodes in He`eia Fishpond

Several low-cost wireless sensor nodes are deployed at He'eia Fishpond, Kāneʻohe Bay, Oahu. The sensor packages are collecting continuous environmental data to better understand physical conditions and biogeochemical cycles in real-time.

The nodes measure a combination of meteorological conditions, such as water depth, conductivity, temperature, dissolved oxygen, turbidity, and chlorophyll. They are deployed at the following locations:

  • node-004 and node-009 at Makaha 1
  • node-007 (a meteorological station) at the Hale at Makaha 2
  • node-008 at Kaho`okele
  • node-014 at River Makaha
  • node-015 at Storm Makaha

node-008, node-009, node-010, node-014, and node-015 are topside ultrasonic sensors measuring water level to corroborate submerged pressure sensors.

All data are presented in near-real-time, and thus are provisional and subject to revision during quality assurance and quality control data processing. More sophisticated data analyses are currently under development. More information on He'eia Fishpond can be found here and here. Full datasets for all sensors at each node are available through links at the left or by exploring the interactive dashboard.
