Abstract
A plant matter sensor comprising: one or more emitters configured to emit two or more vertically spaced signals toward a plant; and one or more receivers configured to receive two or more reflected signals from the plant.
Claims17
A plant matter sensor comprising:
- one or more emitters configured to emit two or more light signals toward a plant matter;
- and
- one or more receivers configured to receive two or more reflected light signals from the plant matter;
- wherein emitters and receivers are arranged together in clusters on an elongate sensor board;
- wherein the plant matter sensor includes a housing configured to minimise ambient light reaching the receivers;
- and
- a processor configured determine health and/or nutritional content based on a ratio between a reflected signal of a first frequency and a reflected signal of a second frequency determined at vertically displaced points on the plant matter.
