An apparatus for remote detection of plant growth dynamics is described. The apparatus includes an excitation LED (light emitting diode) module, a detection module and a controller module coupled to the excitation LED module and the detection module. The excitation LED module includes at least one LED. Each LED is configured to emit an excitation light in response to an excitation control signal. The excitation light has an emitted light spectrum. The detection module includes a photodetector configured to detect an initial chlorophyll a fluorescence (“ChlF”) light and an excited ChlF light from a plant species. The photodetector is further configured to convert the detected initial ChlF light into an initial detection electrical signal and the detected excited ChlF light into an excited detection electrical signal. The excited ChlF light is emitted from the plant species in response to receiving the excitation light. The controller module is configured to provide the excitation control signal to the excitation module, to capture the initial and excited detection electrical signals from the detection module and to determine chlorophyll fluorescence data based, at least in part, on the initial and excited detection electrical signals. The excitation LED module and the detection module are configured to be positioned remotely from the plant species. The chlorophyll fluorescence data represents a growth characteristic of the plant species.

The quality determination device 20 includes a cylindrical grass sending tube 21, a grass taking section 22 configured to feed at least a portion of the pasture grass 1 left in the pasture land to an inside of the grass sending tube 21 via a first end of the grass sending tube 21 and a quality determination instrument 9 configured to determine quality of the pasture grass 1 compressed inside the grass sending tube 21.

System and method of detecting infestation in agricultural products is disclosed. In one embodiment, an infestation detection system captures hyperspectral imaging data and depth imaging data for a plurality of points on an agricultural product upon directing a light source at the agricultural product. The system analyses the captured imaging data to derive morphological details as well as spectral signatures for complete 360° view of the plurality of points on the agricultural product. In an embodiment, the spectral signatures may be corrected for one or more pixels associated with the plurality of points in the agricultural product by integrating the hyperspectral imaging data with the depth imaging data. The system further classifies one or more regions of the agricultural product based on matching of spectral signatures for the one or more pixels with pre-defined spectral signatures stored for a plurality of agricultural products, and accordingly detect infestation.

A produce freshness sensor inexpensive enough to be discarded after each produce use, and multi-functional that is affixed to the produce by the grower that monitors parameters that affects produce freshness (to measure color and chemical composition), the sensor being used throughout the produce distribution system. A sensor monitors produce freshness and comprises one or more emitters, a temperature sensor, a microprocessor, and a transceiver mounted on a printed circuit board. The sensor is affixed relative to the produce. Power usage is critical to prolong operational time of the temperature sensor. Data collection and transmission are controlled to minimize run time and power usage. An initial baseline is established when the sensor is affixed relative to the produce, the start time and baseline measurements being recorded relative to the baseline. The real-time information is subsequently processed to provide analysis and relevant data to users throughout the produce distribution system.
