A new groundwater sensor system developed by the CSIRO promises to make environmental monitoring faster, more reliable and less labour-intensive for the resources industry.

SENSEI is a multi-sensor system capable of simultaneously collecting data on pH, reduction potential, temperature and conductivity. 

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



The robust sensor unit can be embedded into groundwater wells and aquifers and 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 so companies can 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.

CSIRO is looking for partners to bring the technology to market after successful trials at Heathgate Resources’ Four Mile West mine in South Australia.

A prototype unit is on display at the International Mining and Resources Conference in Melbourne this week.
