YSI EXO3 Multiparameter Sonde + Consibio Logger

EJ
Updated

YSI EXO3 is a multi-parameter Sonde, that can be used to measure a multitude of parameters (RDO, pH/ORP, temperature, salinity, turbidity etc.) in remote monitoring of environmental research, aquaculture, drinking water etc.

Together with the Consibio Logger, you can all the parameters in real-time to provide valuable insights for:

  • Holistic Water Quality Assessment: Simultaneously measures key parameters such as temperature, pH, dissolved oxygen, turbidity, and conductivity, providing a comprehensive understanding of water quality dynamics.
  • Ecosystem Health Monitoring: Facilitates the assessment of aquatic ecosystem health by monitoring parameters critical for biodiversity, nutrient cycling, and overall ecosystem functioning.
  • Pollution Detection and Remediation: Enables the detection of pollution sources and the evaluation of remediation efforts by monitoring indicators of contamination such as nutrient levels, organic matter, and turbidity.

Sonde configuration in Kor

Prerequisites

  • Remove the batteries internal to the EXO3-sonde. This counts for both configuration and when deployed in the field integrated with the Consibio Logger. By this, the sonde is powered entirely by the Consibio Logger and timestamps in the Cloud will be aligned with measurements of the sonde.
  • Appropriate sensors installed in the sonde.

Kor software

The YSO EXO3 sonde must be configured in their software platform named "Kor". In Kor, you will have to determine the parameters to be sent over the communication bus and in which order they should be sent.
The software platform can be downloaded from here.
For this tutorial, the software version v.1.4.1.10 was used.

Connecting EXO3 sonde to Kor

Opening Kor, the following user-interface will be presented to you:

  1. Connect the sonde to your PC USB port with the "Signal Output Adapter USB-Sonde" by EXO.
  2. The Kor software will recognize the sonde and it will appear on the left hand side of the screen with the Serial Number/Instrument ID of the sonde.

Deployment of EXO3 sonde

  • Click on the "DEPLOYMENT" tab
  • To create a new template (configuration) to deploy to the EXO3-sonde, click "Create Template"
  • Set up the deployment in the tabs "BASIC DEPLOYMENT SETTINGS" and "ADVANCED" like the following screenshots. This will ensure proper operation. If other configurations are preferred, consult Consibio in order to ensure compatibility. 

  • To setup the sensor parameters, you have to ensure that the appropriate sensors are connected to the sonde. The following screenshot is just an example where the parameters (temperature, turbidity, conductivity, depth and NO3-N) are to be sent to the datalogger. In this example, the parameters will be indexed as: Temperature (index 0), Turbidity NTU (index 1) and so on. 

  • Finish the deployment setting by applying the template to the sonde and start logging:

 

Wiring of Sensor and Logger

Prerequisites:

Connecting a YSI EXO3 sensor via. SDI-12

To integrate the YSI EXO3 sonde with the Consibio Logger via SDI-12, utilize the SDI-12 Expansion Board and follow these connections:

  • Black wire to GND
  • Drain wire / Shield / Bare Wire to GND
  • Red wire to 12V
  • Orange wire to Signal

This configuration leverages the Logger's compatibility with the Serial Digital Interface at 1200 baud (SDI-12) Protocol and the versatility of its SDI-12 Expansion Board, enabling seamless integration with industry-standard communication protocols for efficient data acquisition and monitoring.

Consibio Cloud Configuration

Prerequisites:

In order to read the sonde parameters to Consibio Cloud, first make sure you have:

  • Claimed device into project
  • Added the sensor channel to the port of which the SDI12 expansion-board is connected
  • Configured max offline and measurement interval as wished.

SDI12 channel configuration

The SDI12 channel in Consibio Cloud has to match the sensor address and parameter indexes of which you entered in the deployment in the Kor software. In this example, the channel configuration will look like so:
