641555 external_news 1606144706 1606144706 Using a modest grant of $50,000 from the Georgia Smart Communities Fund, Clark began designing a new type of sea level sensor that’s assembled from a collection of off-the-shelf parts. The sensor is placed on bridges and other infrastructure along the coast. It sends ultrasonic pulses from its high perch down to the surface of the water, using the time it takes for the pulse to reflect off the water’s surface and return to the device to calculate the sea levels. Importantly, the sensor is low-cost and easy to build. An initial network of about a dozen of these sensors is providing real-time data on water levels for the city of Savannah and surrounding Chatham County.
