LilyPad Light Sensor Hookup Guide

The LilyPad Light Sensor is an e-textile friendly version of the Ambient Light Sensor Breakout. If you’ve used the breakout in a project before, the hookup and code will be very similar. You will need to connect to a LilyPad Arduino or other microcontroller to read the sensor values and use in your code. This sensor outputs an analog value from 0 to 5V. In bright light (full daylight) this sensor will output 5V, and if completely covered will output 0V. In a typical indoor lighting situation, the sensor will output from around 1 to 2V.”
