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.
This sensor can capture little change of light!!
Notice:The new version of analog sensor port pin mapping has been changed as the following two features.Please checkthe 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.
