Specifications: The TSL2591 light sensor module features a very high range of digital light sensors. Compared to conventional photoresistors, the TSL2591 light sensor can calculate lux illumination. The module has an infrared sensor and a sensor that captures the entire spectrum. The diodes can be individually controlled so that the infrared component, the entire spectrum or only the visible portion can be measured. The closed pin head can be soldered as needed.
