Adafruit ALS-PT19 Analog Light Sensor Breakout

The ALS PT19 analog light sensor is a top choice for enhancing projects that utilize photocells while ensuring RoHS compliance. With a high rejection ratio of infrared radiation, its spectral response closely mimics that of human eyes, providing accuracy in light detection.

Designed for simplicity, it connects effortlessly – ground to ground, power to a 2.5V-5.5V source, and the OUT pin for analog voltage measurement. As light intensity increases, so does the voltage reading, making it a straightforward yet effective tool for light-sensitive applications.
