2. Soldering the headers Before using your click board, make sure to solder 1x8 male headers to both left and right side of the board. Two 1x8 male headers are included with the board in the package. 1 Illuminance click 4. Essential features 2 3 The TSL2561 sensor on Illuminance click is designed to mimic the way humans perceive 1. Introduction light. Conventional light sensors are too sensitive to infrared light to be suitable for measuring ambient lightning. The sensor on Illuminance click has two photodiodes. One is sensitive to the full-spectrum of light, the other to infrared light only. The visible-spec- Turn the board upside down so that Turn the board upward again.
