University professor turns smart phones into smart sensors

Dr. Krishna Nemali, Assistant Professor and Extension Specialist at Purdue University, has developed an easy-to-use, affordable smart sensor that’s proving valuable to indoor farmers for improving farm productivity and crop quality.

Using only a smartphone and a connection to Dr. Nemali’s apps, users can quickly and precisely monitor/measure a wide variety of production and growth parameters including light efficiency, germination rate, plant size (area, height, weight), color (intensity, progression), damage (nutrient deficiency, insect), biochemistry (chlorophyll, nitrogen and other micronutrients), and stress index.

Dr. Nemali plans to make his smart sensor tool available in January 2022 for a nominal annual fee, which will support the development of future applications. You can see the complete video here.
