DESCRIPTION

Add a teeny analog light sensor, the ALS PT19 analog light sensor is a great way to

upgrade a project that uses a photocell and needs RoHS compliance. Due to the

high rejection ratio of infrared radiation, the spectral response of the ambient light

sensor is close to that of human eyes.

It's a pretty simple sensor - connect - to ground, + to 2.5V-5.5V or so to power it.

Now measure the analog voltage on the OUT pin. That's it! The voltage will increase

when the sensor detects more light.
