On October 15, 2024, LPES Laboratory had the privilege of participating in the Wisconsin Science Festival. During the event, we engaged young students by showcasing various scientific concepts and technologies. Our demonstrations included the natural nitrate cycle, an Arduino-based soil moisture sensor, and a cutting-edge soil nitrate monitoring device developed using printed electronics technology. We are honored to have been part of this inspiring event and look forward to participating in similar future endeavors. Below are some photos from the event.
