Mobile Water Purity Tester (MWPT)
PROJECT GOAL: Our goal with this design was to provide an affordable alternative to expensive single-use water purity testers. Furthermore, a simple interface and usability is a requirement to allow for more users to be able to pick up the device and use it easily, without having to learn anything new.
In order to address water quality access issues, we created an Arduino-based water quality tester that measures pH, electrical conductivity, temperature, and turbidity. Because the prototype is small, portable, and inexpensive, our project can expand access to water quality testing. In this current iteration, the device is able to record data from the probes onto an SD card, present data through an interface, and connect to a companion app to show relative levels of safety.
