Many plants change color due to growth or environmental stress. We thought it would be useful to be able to control growth environment by using color changes in the plant's surface layer.
We developed a color sensing system that can continuously measure color change of a plant's surface layer.
This sensing system is composed of an optical fiber, a halogen lamp, a semiconductor color detector and an electronic circuit. It outputs DC voltage that reflects color onto the surface layer of plants.
