How sensors simplify data collection in development cooperation

A project from Portland State University and the London School of Hygiene &Tropical Medicine used IoT technology to analyse sanitation standards in Bangladesh and India. Sensors were installed in over 1200 households to record movement and water flow in the ‘restroom’ (that is to say, the latrines). The data compiled showed how the latrines were being used, and served as the basis for improvements made to the sewage and sanitation systems. The project exemplifies how the use of low-cost sensors can significantly streamline the collection of data for development aid projects.
