Description: The TSL2561 Luminosity Sensor Breakout is a sophisticated light sensor which has a flat response across most of the visible spectrum. Unlike simpler sensors, the TSL2561 measures both infrared and visible light to better approximate the response of the human eye. And because the TSL2561 is an integrating sensor (it soaks up light for a predetermined amount of time), it is capable of measuring both small and large amounts of light by changing the integration time.

The TSL2561 is capable of direct I2C communication and is able to conduct specific light ranges from 0.1 - 40k+ Lux easily. Additionally, the TSL12561 contains two integrating analog-to-digital converters (ADC) that integrate currents from two photodiodes, simultaneously. Each breakout requires a supply voltage of 3V and a low supply current max of 0.6mA.

TSL2561是光-数字转换器，它将光强转换成数字信号输出，具有直接I2C接或者SMBus接口。每个设备都连接一个带宽的光敏二极管和在单独CMOS集成电路上的一个红外响应的光敏二极管，这个集成电路具有提供20bit动态范围的近-适光响应的能力。两个集成的ADCs将光敏电流转换成一个数字输出，这个数字输出表示测量每一个通道的发光。这个数字输出可以S一个微处理器的输入。

TSL2561是TAOS公司推出的一种高速、低功耗、宽量程、可编程灵活配置的光强度数字转换芯片。该芯片可广泛应用于各类显示屏的监控，目的是在多变的光照条件下，使得显示屏提供好的显示亮度并尽可能降低电源功耗；还能够用于街道光照控制、安全照明等众多场合。该芯片的主要特点如下：

1.可编程配置许可的光强度上下阈值，当实际光照度超过该阈值时给出中断信号；

2.数字输出符合标准的SMBus(TSL2560)和I2C(TSL2561)总线协议；

3.模拟增益和数字输出时间可编程控制；

4.低功耗模式下，功耗仅为0.75 mW

5.自动抑制50 Hz/60 Hz的光照波动。
