Low Cost Electronic Algae Detection

The detection of harmful algae blooms (HABs) has caused problems for areas relying on Lake Erie for water. Improper detection led to the 2014 water crisis for Toledo, Ohio and surrounding areas. Since then new detection methods have been developed but are too costly to be applied a crossed Lake Erie. Present in this paper is a low-cost method for remote detection of algae. This project’s purpose was to design and fabricate a mass producible detector to be used by health officers and assist in further research and relief efforts along Lake Erie. The detector is comprised of four sensors, chlorophyll, turbidity, conductivity, and color. The sensors work together to take and verify readings of algae. The cost of a detector complete with sensors and the communication system costs $75 with a $60 gateway receiver.
