Leaf & Bud Temperature Sensor

Leaf & Bud Temperature Sensor innovatively tracks temperature. Designed to mimic leaves and flower/fruit buds, so will track their temperature when it drops below the ambient air temperature so the grower can activate frost protection equipment in time to protect crops safely and economically.
