For her Gold Award, Rajvi, 18, from Girl Scouts of Northern California, developed soil moisture sensors and readers to help farmers conserve water and use less groundwater. The sensors are planted into the soil; they allow farmers to read and determine the moisture level in the soil. Based on Rajvi's technology, farmers on average saved 25 percent of their monthly water use and were able to better sustain their businesses during the California drought.
She has since received a provisional patent on her product and is now working to make it accessible for all. Her project is available on Facebook and YouTube as a video log to show people how the technology works and how they can replicate it globally in areas affected by drought. She has also made it cost effective so that farmers in rural or underserved communities can benefit from it. Ravji even got the opportunity to share her project at Oracle Openworld, one of the leading technology conferences in the world. She’s unstoppable!
