Illuminance click carries a TSL2561 light-to-digital converter with a sensor that’s designed to mimic the way humans perceive light. This makes it ideal for applications where ambient lighting conditions have to be measured (backlight power-saving on LCD displays for example). The sensor has two photodiodes. One sensitive to full-spectrum light, the other to infrared. The visible-spectrum is then deduced by using a formula. Illuminance click communicates with the target board through mikroBUS I2C lines, and uses a 3.3V power supply.
