Parameters:

• The LilyPad Light Sensor is a sewable breakout board with an ALS-PT19 light sensor built in and ready to use right away. 

• Each sensor outputs voltage between 0V and 3.3V depending on the level of ambient light shining on it. 

• As more light is applied on the sensor, more current will flow from the board through the signal tab to the microcontroller you connect the sensor to. 

• If the sensor receives no light, no current will flow through it. In a typical indoor lighting situation, the sensor will output around 1 to 2V. 

• Adding this board into your next e-textile or wearable project will really open up the possibilities by being able to incorporate light level sensing capabilities.
