Appropriate for all ages? Yes

Description:
Approximately 40% of the world population (2.6 billion people!) has no access to adequate sanitary toilet systems. Diarrheal diseases kill 1.8 million people every year and 90% of those who die are children under the age of 5. This translates to a death every twenty seconds from a preventable disease. This situation affects mostly developing and under developed regions of the world. In Haiti, nearly 75% of the population lives on less than $2 a day and only 10% of rural Haitians have any form of improved sanitation (such as a latrine). Because of poverty, poor infrastructure, and low levels of education, it is difficult to implement sanitation solutions that work and have a widespread impact. An arborloo is a movable pit latrine that composts human waste into organic fertilizer to provide nutrients for a fruit tree. It is an inexpensive and simple design that helps decreases the spread of pathogens present in human feces. This composting process can only occur under the right conditions of temperature, humidity, soil acidity, and oxygen content. Our system continuously monitors the conditions of 100 arborloo pits, as well as the frequency of their use, and stores the data for later retrieval. This data is then downloaded onto a device running an app developed by a member of our team for consolidation and analysis. This data can then be used to determine whether or not the arborloo is properly composting the human waste to the necessary degree. Experience a mock-up of our system, including a detailed dive into the electronics and theory of how to keep a low-power system running for 45 days on just 3 batteries, basic ergonomics of seat design, and other topics.
