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: An optical sensor device includes a light emitter for emitting, to a living body, lights having two wavelengths and blinking at a predetermined frequency, and a light receiver for receiving the lights from the living body. The light receiver outputs first and second detection signals corresponding to the respective wavelengths. A filter circuit extracts, from the first and second detection signals, modulation signals that are obtained with amplitude modulation of signals of the predetermined frequency. The modulation signals are amplified by a post-amplifier and are taken into an arithmetic processing unit after being converted to digital signals by an AD converter. The arithmetic processing unit calculates DC components and AC components of the first and second detection signals by employing the modulation signals converted the digital signals.

Abstract: A device (1) for determining the concentration of a gas component is configured with a radiation source (30) for radiating (31) light as a light emission in an infrared wavelength range. Two detector arrays (52, 62) with two detector elements (50, 60) are configured suitably for detecting the light emission generated by the radiation source (30) in two detector arrays (52, 62). Two filter elements (51, 61) are associated with the detector elements (50, 60). The two detector elements (50, 60) are oriented in relation to the radiation source, so that a range of overlap (65) is obtained due to the two detector arrays (52, 62). The range of overlap (65) causes attenuations in the propagation of light, which may be due to gas molecules or moisture (400). The attenuations in the propagation of light affect both detector elements (50, 60) and are compensated concerning the determination of the concentration.
