In this episode of Hardware to Save a Planet, Dylan is joined by Patrick Kiely, CEO of Sentry, a biological activity and water quality monitoring sensor platform. The conversation pivots around improving wastewater treatment in the context of climate change. We discuss the importance of reliable water quality data to optimize the water treatment process and how Sentry's sensor platform measures the health of bacteria in wastewater environments. Patrick also highlights the potential of wastewater treatment plants to become net-positive energy generators through the use of biogas.
