TSL2583傳感器變送器的光學傳感器-環(huán)境光IR紅外線UV紫外線傳感器規(guī)格書PDF中文資料

Description

The TSL2581 and TSL2583 are very-high sensitivity light-to-digital converters that transform light intensity to a digital signal output capable of direct I2C interface. Each device combines one broadband photodiode (visible plus infrared) and one infrared-responding photodiode on a single CMOS integrated circuit capable of providing a near-photopic response over an effective 16-bit dynamic range (16-bit resolution). Two integrating ADCs convert the photodiode currents to 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 TSL2581 device supports a traditional level style interrupt that remains asserted until the firmware clears it.
