GY-2561 TSL2561 光強度感測器 模組 含Arduino  範例與函數庫

TSL2560和TSL2561是光數字轉換器，可將光強度轉換為能夠直接I2C（TSL2561）或SMBus（TSL2560）接口的數字信號輸出。每個器件在單個CMOS集成電路上組合一個寬帶光電二極管（可見光和紅外線）和一個紅外響應光電二極管，能夠在一個CMOS上提供近光響應。
有效的20位動態範圍（16位分辨率）。

兩個積分ADC將光電二極管電流轉換為數字輸出，表示在每個通道上測量的輻照度。這個數字輸出可以輸入到微處理器
使用經驗公式導出lux中的照度（環境光水平）以近似人眼響應。 TSL2560器件允許SMB-Alert樣式中斷，TSL2561器件支持傳統的電平樣式中斷，該中斷在固件清除之前保持有效。

雖然TSL2560 / 61器件適用於通用光傳感應用，但它專為顯示器面板（LCD，OLED等）而設計，旨在延長電池壽命並在各種照明條件下提供最佳觀察效果。顯示面板背光可佔自動平台總功率的30％至40％，可自動管理。兩種設備也是基於環境照明條件控制鍵盤照明的理想選擇。照度信息還可用於管理數碼相機中的曝光控制。 TSL2560 / 61器件是筆記本電腦/平板電腦，液晶顯示器，平板電視，手機和數碼相機的理想選擇。此外，其他應用包括路燈控制，安全性
照明，陽光采集，機器視覺和汽車儀表集群。

The TSL2560 and TSL2561 are light-to-digital converters that transform light intensity to a digital signal output capable of direct I2C (TSL2561) or SMBus (TSL2560) 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 20-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 TSL2560 device permits an SMB-Alert style interrupt, and the TSL2561 device supports a traditional level style interrupt that remains asserted until the firmware clears it.

While useful for general purpose light sensing applications, the TSL2560/61 devices are designed particularly for display panels (LCD, OLED, etc.) with the purpose of extending battery life and providing optimum viewing in diverse lighting conditions. Display panel backlighting, which can account for up to 30 to 40 percent of total platform power, can be automatically managed. Both devices are also ideal for controlling keyboard illumination based upon ambient lighting conditions. Illuminance information can further be used to manage exposure control in digital cameras. The TSL2560/61 devices are ideal in notebook/tablet PCs, LCD monitors, flat-panel televisions, cell phones, and digital cameras. In addition, other applications include street light control,  ecurity
lighting, sunlight harvesting, machine vision, and automotive instrumentation clusters.
