Analog Light Sensor Product Description

This small 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.

As a simple sensor, all you’ll need is to connect to ground and to 2.5V-5.5V to power it up and you can start measuring the analog voltage on the OUT pin. As lighting increases, so will the voltage.
