摘要： PROBLEM TO BE SOLVED: To provide a sensor apparatus for plants which simplifies the constitution, reduces an effect of a light quantity component due to a disturbance light, simplifies the constitution of an optical system, and correctly and accurately measures the reflectivity of an object whose growing condition is to be measured. SOLUTION: The sensor apparatus includes a light source section 4, comprising a first light-emitting section 9 for periodically emitting a light, and irradiating the object 3 whose growing condition is measured with a first measurement light P1, whose peak wavelength of the light emission intensity is a first wavelength; a second light-emitting section 10 for periodically emitting a light, and irradiating the object 3, whose growing condition is measured with a second measurement light P2, whose peak wavelength of a light emission intensity is a second wavelength; and a light-receiving section 6 for receiving the reflected light from the object 3, whose growing condition is to be measured; a control section for controlling the lights emitted from the first and second light-emitting sections 9, 10 at different timing, an integration-control section 24 for integrating a light reception signal from the light receiving section 6, and outputting an integration signal, and a calculation section 13 for calculating the reflectivity as the ratio of the light quantity of the reflection light to the light quantity of the respective measurement lights P1, P2, and obtaining information, on the growing condition of the object 3 whose growing condition is measured, based on the integration signal from the integration-control section 24.
