The Commonwealth Scientific and Industrial Research Organisation (CSIRO) recently announced a new in-situ groundwater monitoring solution for real-time data monitoring and management. Sensei is a multi-sensor system capable of simultaneously collecting data on pH, reduction potential, temperature and conductivity, the organization says.

“Sensei is an automation system which delivers reliable groundwater data in real time, saving companies time and money on labor from traditional manual monitoring approaches,” CSIRO research leader Dr. Kathie McGregor said in a statement.

The solid-state multi-sensor array features CSIRO's pH sensor and reference electrode innovation based on advanced sensor chemistry and materials. It can be embedded into groundwater wells and aquifers to deliver continuous data for months without the need for manual calibration or maintenance. Third-party sensors can also be integrated into the systems attached to the solid-state multi-sensor array.

With real-time analytical capability, Sensei can provide early alerts to help companies mitigate environmental issues arising in groundwater management.

"Because data can be accessed immediately on-site or remotely via the cloud, the user has the ability to detect any anomalies quickly and take action as soon as possible," Dr McGregor said.

Sensei was built to withstand extreme environments and was successfully trialed at Heathgate Resources' Four Mile West mine in South Australia.

CSIRO says that the solution could be adapted for other applications that need chemical and physical monitoring in extreme environments.
