Description
The KY-027 Magic Light Cup Module is a light-sensitive detection module designed to respond to changes in ambient light intensity. Based on a Light Dependent Resistor (LDR) and comparator circuit, it provides a digital output signal that can trigger actions when light levels cross a set threshold.
With an onboard potentiometer for sensitivity adjustment, this module is ideal for automatic lighting systems, interactive electronics, and educational projects.
