描述
Grove – Digital Light Sensor 數字型光感測器 紅外模式、全光譜、人類可見模式
該模組基於 I2C 光轉數字轉換器 TSL2561 將光強度轉換為數字信號。與傳統模擬光傳感器（Grove-Light Sensor）不同，該數字模組具有可選擇的光譜範圍，因為其具有雙光敏二極管：紅外和全光譜。 您可以在三種檢測模式之間切換以獲取您的讀數。它們是紅外模式，全光譜和人類可見模式。當在人類可見模式下運行時，這個傳感器會給你提供與你的眼睛感覺接近的讀數。

This module is based on the I2C light-to-digital converter TSL2561 to transform light intensity to a digital signal. Different from traditional analog light sensor, as Grove – Light Sensor, this digital module features a selectable light spectrum range due to its dual light sensitive diodes: infrared and full spectrum. You can switch between three detection modes to take your readings. They are infrared mode, full spectrum and human visible mode. When running under the human visible mode, this sensor will give you readings just close to your eye feelings. Features
- Selectable detection modes
- high resolution 16-Bit digital output at 400 kHz I2C Fast-Mode
- Wide dynamic range: 0.1 – 40,000 LUX
- Wide operating temperature range: -40°C to 85°C
- Programmable interrupt function with User-Defined Upper and lower threshold settings
Application Ideas
- Ambient light sensing
- Backlighting control for display panel
- Keyboard illumination control
