      Description

      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

      Hi Im using a grove with TSL2561 sensor, but this grove dosn't have an address, how can I wire 2 or more of this?
      Note Im wiring directly to the arduino, i want to wire 10 sensors

      You can use an I2C multiplexor to connect 8 sensors of the same I2C address to one I2C buss (I2C address 0x70-0x77) using Adafruit TCA9548A board. To do 10 sensors, you would need two multiplexors set to different I2C addresses, and your 10 sensor boards connected to the multiplexor boards, with all of them having the same I2C address. How it works: You write to the multiplexor I2C address and tell it which of the 8 boards to select, then you write to the sensor address and get the value from that one board, then to be safe (as to not have two of them turned on at once) you write to the multiplexor and turn them all off. By repeating this process for each sensor, you should be able to poll all ten sensors in about half a second.

      Can the i2c address of this module be changed so I may have multiple on the same buss?

      <p>Hi James.You might not change the address of I2C beacuse of the setting in circuit.</p>

      I am guessing I have to connect this to 3v. But I would like your advice.
      Thank you

      <p>Hi ,both of 5v and 3v3 can be use , because the input voltage it 2.7 - 5v</p>
