Frame with sensors for sampling honeycomb content based on the method of absorption spectroscopy

A frame (1) with a plurality of photoelectric sensors (3) for sampling a contents of a honeycomb, based on absorption spectroscopy, the frame (1) comprising:

• a honeycomb base (2) comprising two cover plates (8), the plurality of photoelectric sensors (3), and a wire bus (4), wherein the plurality of photoelectric sensors (3) and the wire bus (4) are disposed between the two cover plates (8);
• a central microprocessor with a memory (5) connected to the plurality of photoelectric sensors (3) by the wire bus (4);
• a power supply unit (6) connected to the central microprocessor with the memory (5);
• and
• a communication subsystem (7) connected to the central microprocessor with the memory (5),
• wherein each photoelectric sensor (3) comprises an infrared diode and a silicon phototransistor, the infrared diode being arranged to emit an infrared light beam toward the contents of the honeycomb, and the silicon phototransistor being arranged to measure reflected light from the contents of the honeycomb, and
• wherein the central microprocessor with the memory (5) determines, based on an amount of the reflected light measured by the plurality of photoelectric sensors (3), whether the contents of the honeycomb comprise empty honeycomb, honey, pollen, or bee brood.
