The TSL2591 light sensor is an advanced digital light sensor, suitable for use in various light conditions. Compared to low-cost cadmium sulfide cells, this sensor is more accurate, allowing precise lux calculations and configurable for different gain/timing ranges, with a 188 DULUX light detection range up to 88,000 lux at a flying distance. It contains both infrared and full-spectrum diodes, which can measure infrared, full-spectrum or human visible light respectively. The TSL2591 light sensor has a huge dynamic range of 600 million:1. Please note that compared to the previous TSL256 1, the 7-bit I2C address (0x29) of the sensor cannot be changed. The board has a voltage regulator and can work at a voltage of 3.3V-5.0V. The built-in ADC device can take advantage of this with any microcontroller, even if it does not have an analog input. Actively sense 0.4mA, less than 5μA in power-down mode. The device current consumption is extremely low, so it is very suitable for low-power data recording systems.
