TSL2584TSV Digital Ambient Light Sensor Module TSL2584 Light Intensity Light Sensor I2C CommunicationItem NO.: TSL2584TSV

TSL2584TSV Digital Ambient Light Sensor Module

Product Introduction：

The TSL2584TSV is a very-high sensitivity light-to-digitalconverter that transforms light intensity into a digital signaloutput capable of direct I²C interface. The device combines onebroadband photodiode (visible plus infrared), oneinfrared-responding photodiode, and a photopicinfrared-blocking filter on a single CMOS integrated circuit. Twointegrating ADCs convert the photodiode currents into a digitaloutput that represents the irradiance measured on eachchannel. This digital output can be input to a microprocessorwhere illuminance (ambient light level) in lux is derived usingan empirical formula to approximate the human eye response.The TSL2584TSV supports a traditional level style interrupt thatremains asserted until the firmware clears it.
