What are the uses of light sensor module chips
Light sensors come in several types, each with a characteristic output signal (resistance / current / voltage / I²C/SPI) and preferred use cases (ambient light, RGB color, UV monitoring, proximity/ToF distance). A light sensing sensor (also called a light sensor, photodetector, or ambient light sensor—ALS) converts light into an electrical signal. In practice it is built in two ways: a discrete analog chain or an all-in-one sensor IC. Seems simple? There is more to a light sensor than just its definition. TI's optical light sensors with integrated photo sensor and passive filters offer excellent spectral matching, low power, and configurable conversion times.

Temperature drift of fiber optic grating temperature sensor
In this paper we review the literature related to the long-term wavelength drift of FBGs at high temperature and provide our recent results of more than 4000 h of high temperature testing in the 900–1000 °C range. The regenerated fiber Bragg grating was produced by annealing a “seed” fiber Bragg grating recorded on SMF-28 hydrogen-loaded. This example demonstrates a temperature sensor based on fiber Bragg gratings (FBG). The temperature-dependent change of the refractive indices of the fiber, consequently the shift of its Bragg wavelength, is used as a measure of the temperature. Due to their small size, capacity to be multiplexed into high density distributed. A Fibre Bragg Grating (FBG) is a device that allows light to be reflected from a short section of optical fiber at a specific wavelength, while the Bragg reflector expands and transmits all other wavelengths.
