Want to know how your compost is faring? A local teen has created a device to do just that

A local high schooler’s science fair project turned into a nationally recognized innovation.

Recent Walnut Hills graduate Angelina DiPaola began experimenting with sensors and composting in eighth grade.

“I didn't have a very successful science fair,” DiPaola said. “All the bins turned out very smelly and made my basement completely uninhabitable. But I did come away with the idea that, 'Oh, I could use sensors to help people start composting.' ”
