The Grady Seed Moisture Sensor
A portable near-infrared (NIR) sensing device that measures grass seed moisture content in seconds, replacing a time-consuming lab drying process. Calibrated for eight cool-season grass seed species and achieving a mean error of 1.2–4.6%, the Grady Sensor enables timely, field-side harvest decisions.
