The Illuminance Click Board™ from MikroE is a light sensor designed for better detection of ambient lighting over conventional light sensors that are too sensitive to infrared light. The board features an on-board TSL2561, a light-to-digital converter, which transforms light intensity to a digital signal output. The TSL2561 sensor uses two separate photodiodes: One is sensitive to the full-spectrum of light, the other to infrared light only. Using a formula, the user gets a sensor reading then approximates light response of the human eye. Illuminance Click Board™ communicates with your target microcontroller via MikroBUS I2C lines: SCL (clock) and SDA (data). The zero-ohm J1 jumper allows the user to select between three available I2C address.

The Illuminance Click finds application in auto-brightness regulators on OLED or LCD displays, or any other kind of automatic ambient light regulation. It is designed to use a 3.3V power supply only.

  • Based on the TSL2561
  • Two photodiodes: infrared and full-spectrum
  • Mimic the way humans perceive light
  • I2C communication interface
  • 3.3V power supply
  • Compact design
  • RoHS Compliant
  • Supported by all mikroElektronika compilers

Product Details

IC/Module: TSL2561

Designed to approximate the way human eye responds to light, TSL2561 sensor features a programmable interrupt function with user-defined upper and lower threshold settings. With I2C fast-mode at 400 kHz, it has low active power consumption with power down mode.

TSL2561: Light-to-Digital Converter

TSL2561 is a light-to-digital converter that converts light received through two photodiodes into a digital signal using two integrating analog-to-digital converters (ADC). This digital output works as input to the microprocessor where illuminance (ambient light level) is derived as a sensor reading, using an empirical formula to approximate the human eye response.

I2C Address Selection

Illuminance Click features a jumper J1 that provide user the option to select between three available I2C addresses. The user can choose an address by changing the jumper position between logic 1 and logic 0. By default, it's on logic 1.
