TSL2591 High Dynamic Light Sensor Breakout Module 3V 5V I2C High Range Optical Sensor Development Tool

TSL2591 optical sensor is an advanced digital light sensor that is suitable for use under various light conditions. Compared with low -cost cadmium sulfide cells, this sensor is more accurate, allowing accurate Lex computing and configuration to different gain/timing range, to detect the 188 dulux light detection range of 88,000 Lax. It also contains infrared and full -spectrum diode, which can measure infrared separately, full spectrum or human visible light. TSL2591 light sensor has a huge 600 million: 1 dynamic range. Note that compared with the previous TSL2561, the 7 -bit 12C address (0x29) of the sensor cannot be changed. The board has a regulator and can work at a voltage of 3.3V-5.0V. The built-in ADC device can use any microcontroller, even if it does not have analog input. At the time of active sensing 0.4 mAh, it is less than 5 micro -safety in the power loss mode. The device current consumption is extremely low, so it is very suitable for low -power data recording systems.

• The TSL2591 is a very-high sensitivity light-to-digital converter that transforms light intensity into a digital signal output capable of direct I2C interface
• The device combines one broadband photodiode (visible plus infrared) and one infrared-responding photodiode on a single CMOS integrated circuit.
• Two integrating ADCs convert the photodiode currents into a digital output that represents the irradiance measured on each channel.
• This digital output can be input to a microprocessor where illuminance (ambient light level) in lux is derived using an empirical formula to approximate the human eye response.
• The TSL2591 supports a traditional level style interrupt that remains asserted until the firmware clears it.
