Shop name:Chong Qing Shuo Yue Ke Ji You Xian Gong Si The TSL2591 light sensor is an advanced digital light sensor, suitable for in various light conditions. Compared to low-cost cadmium sulfide cells, this sensor is more , allowing precise calculations and configurable for different gain/timing ranges, with a 188 light detection range up to 88,000 at a 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 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 -in 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 - mode. The device current consumption is extremely low, so it is very suitable for low- data recording systems. Interface type: IIC Voltage range: 3.3V-5V Dynamic range count: 1 600,000,000 range: 188 uLux sensitivity, up to 88,000 input measurement.
