Grove – Digital Light Sensor 數位型光敏感測器 偵測光亮強度感測器

商品說明

Grove – Digital Light Sensor 數位型光敏感測器 – 偵測光亮強度傳感器

支援 Arduino 與 Raspberry Pi

Grove – Digital Light Sensor 數位型光敏感測器 是基於I2C 光度- 數位 轉換器, TSL2561 將光強度轉換為數位信號。不同於傳統的模擬式光傳感器，數位光敏模組的特點是由於其雙光敏二極管，可選擇的光譜範圍：紅外線和全光譜。您可以在三種探測模式之間切換，把你的讀數。他們是紅外模式，全方位和人類可見模式。當人類可見模式下運行，該傳感器會給你的讀數只是接近你的眼睛感受。

Grove – Digital Light Sensor

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
