The Arborloo latrine is a portable restroom facility which provides a desirable solution for the deposit and sanitary decomposition of human waste products, which can then be used as fertilizer for a fruit tree. The Arborloo design has been completed and is ready for field testing, but currently relies on self-reporting data which has been found to be unreliable. Also, the potential environmental impact of the human waste, currently, has no way of being assessed.

The goals of this project are to design an inconspicuous module which records the number of actual use events as well as periodically measuring and recording the pit conditions for later retrieval. Monitored conditions include humidity, temperature, PH, and oxygen levels. The expected end result is an operational prototype which can be replicated and installed in a number of latrines. The module needs to satisfy size, power usage, manufacturing and operational cost, ease of installation and use, and accuracy constrains to provide a practical solution for the stakeholders.
