Here comes DFRobot's new Analog Ambient Light Sensor. Brand new design and much
more convenient to use.This module help you to detect the light density and reflect
the analog voltage signal back to Arduino controller. You can set the threshold
of voltage level to trig other unit on Arduino project. We also use the enviromental
PT550 light sensor and it is more sensitive to light than normal one. Place check
following improvement we made. We always devote to bring better user experience.
Notice:The new version of analog sensor port pin mapping has been changed as the
following two features.Please check the tips for changing sensor cable pin mapping
while using the I/O Expansion shield. We will continue to update. For the inconvenience
caused, please understand.
