WaterTALK is an online experience driven by Internet of Things (IoT) technology. Nowadays, water treatment workers often monitor important equipment remotely. WaterTALK reflects this shift, allowing students to remotely monitor a small-scale water experiment. Students can interact with the experiment remotely to explore acidity, water pollution, and other simple experiments that all give real-time video and sensor data, as if the student were monitoring a real wastewater treatment system.
