Analog Light Sensor Breakout from Adafruit

Analog light sensor that is a great 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.

Technical Description

connect – to ground, + to 2.5V-5.5V or so to power it. Measure the analog voltage on the OUT pin. That’s it! The voltage will increase when the sensor detects more light.

Limitation

Simple sensor that can only detect ambient light that are on par with human eyes

Skill

Easy
