The develop4wash team has been working on constructing a self-contained, sealed turbidimeter using off-the-shelf components. Progress Here’s what it looks like so far: Internally, the unit is powered by an Arduino Uno microprocesser/development board and two TSL2561 luminosity sensors from Adafruit. Bluetooth connectivity is provided by a Virtuabotix Bluetooth module. […]

Building the Testbed We made a wooden block to keep the relative positions of the sample, sensor, and light source constant as we swap out samples: Originally we attempted to use a 3mW board-powered laser as the light source, but it was not powerful enough to generate any meaningful differences […]
