Abstract: To provide a method of measuring a state of concrete capable of easily determining or measuring deterioration of the concrete without using a spectroscopy while maintaining the estimation accuracy. The method of the present disclosure emits an irradiation light to the concrete, the irradiation light including a wavelength range of near infrared light related to concrete measurement; and receives a reflection light of the irradiation light P reflected on the concrete. The method determines at least five wavelengths λ1 to λ5, λ6 to λ10, different from each other by PLS regression analysis within a wavelength range of 900 nm to 2500 nm of absorption spectrum, and estimates a degree of neutralization of the concrete caused by calcium hydroxide and a concentration of chloride ion.

Abstract: A plant wavelength sensor device includes a light emission portion for emitting a measurement light P to irradiate a target plant, a light receiving portion for receiving the measurement light reflected on the target plant as a reflected light; and a control section for controlling the light emission portion and the light receiving portion. The control section is configured to emit the measurement light having a wavelength range corresponding to a selected growth parameter from the light emission portion, to receive the reflected light from the target plant with the light receiving portion with respect to the measurement light having the wavelength range corresponding to the selected growth parameter, and to calculate a volume of the reflected light from the target plant as a reflected light volume with respect to the wavelength range corresponding to the growth parameter.

Abstract: To provide a plant sensor device capable of obtaining a parameter to determine a growth status other than a spectroscopy vegetation index without increasing its configuration. The plant sensor device includes a light emission part for emitting a measurement light to irradiate a target plant, a light receiving part for receiving a reflected light from the target plant, and a control section for controlling the light emission part and light receiving part. The control section determines a spectroscopy vegetation index of the target plant by obtaining a reflection rate of the target plant based on the measurement light and reflected light. The control section calculates a distance from the target plant to the light emission part in accordance with the measurement light and reflected light, and determines a plant height of the target plant based on the distance.

Abstract: A growth information management apparatus is provided, which can accurately ascertain a growth situation of plants or the like regardless of a positional change of an equipment where the apparatus is mounted. A growth information management apparatus 100 emits a measuring beam to a plant P and acquires growth information on the plant, based on received reflected light, with the growth information management apparatus being mounted on another equipment 1. The growth information is corrected based on change information on the irradiation direction of the measuring beam according to a positional change of the other equipment.
