CELERY2 REFRACTOMETER SENSORS

A palm-sized, celery stalk-shaped optical device that uses the principles of refraction to instantly analyze food freshness and hydration levels. Dubbed the Celery2 Refractometer, this sleek, plant-inspired tool bends light through a food sample—like fruit juice, leafy greens, or even plant sap—measuring sugar content (Brix levels) and water purity with lab-grade accuracy. Designed for urban farmers, gardeners, and health-conscious consumers, the sensor glows green when produce is fresh and well-hydrated, shifts to amber for aging quality, and red when spoiled. The stem-like body houses a micro-prism array and LED refraction guide, while the base slots into a smartphone dock to log data over time via companion app. Built from recycled bioplastics and solar-recharged optics, the Celery2 combines biomimicry and precision science to turn food inspection into a fast, intuitive ritual. It refracts more than light—it refracts how we trust our food.
