Ltr390-uv-01 can be used to measure ultraviolet and visible light of human eyes UV sensor (c) has the characteristics of sensitive sensing, fast response and small volume. Its core sensor ltr390-uv-01 is integrated in expansion board, which can be easily integrated into the equipment. UV sensor (c) is an digital UV sensor expansion board equipped with ltr390-uv-01. It can be used to measure ultraviolet and visible light of human eyes and output light intensity data. Built in ADC can directly output light intensity through interface, which is not easy to be by noise. It has the function of interrupt output and programmable upper and lower threshold The on-board level conversion circuit is compatible with the working level of 3.3v/5v, Manufacturer: Vjsujehgy
