LuxLogger with TSL2561

Tags: TSL2561, FEATHER 32U4 ADALOGGER, Arduino, I2C, SPI, luminosity, lux, IR

Simple data logger based on ADAFRUIT FEATHER 32U4 ADALOGGER with luminosity sensor TSL2561 on an ADAFRUIT breakout board. Programming language is C++ (Arduino sketch). Four different functions are available by selecting them with the help of a 4 Bit DIP switch. 100 text files with acquired data can be stored on the SD card.

Functionality:

• Read luminosity data (lux) from sensor and store it as string value on SD card
• Read all data from all text files from SD card and send it via USB serial to terminal program
• Read directory from SD card and send it via USB serial to terminal program
• Toggle logging/no logging with DIP switch
• Delete all stored text files on SD card
• Blink some error codes with the internal LED if necessary
