I worked with a team of environmental engineering students to design a system to reduce water use while showering. We designed and fabricated a working prototype to encourage shorter shower times. The IoT in-shower device analyzes the ambient audio signature of the bathroom to determine shower times and extrapolate water usage. The device encourages the user to log-in to view their shower goal time as well as display a visual timer and provides audio cues to encourage more mindful showers. The device connects to an online interface that allows for personal customization and group competition.
A works-like Raspberry Pi product prototype.
