TSL2591 High Dynamic Range Digital Light Sensor SIM900 Expansion pinheader: all the IThe TSL2591 light sensor module features a very high range digital light sensor ideal for a variety of use scenarios. Compared to conventional photoresistors, the TSL2591 light sensor allows the calculation of the exact illuminance in Lux and can be configured for use in the measurement range from 188 Lux to 88,000 lux. The module has both an IR sensor and one that captures the entire light spectrum. The diodes can be controlled separately, which
