SCH PHOTORESISTOR LDR SENSOR MODULE (GL4526, 4MM)

Product Description

Product Overview

Bring light-sensing capabilities to your projects with the SCH GL4526 Photoresistor. Also known as a Light Dependent Resistor (LDR) or cadmium sulfide (CdS) photocell, this miniature 4mm through-hole sensor exhibits a variable resistance that changes seamlessly depending on the surrounding light levels.

Key Features

• Premium Sensitive Element: Reliable CdS construction responds quickly to shifts in luminance with a spectral peak mimicking the human eye.

• Ultra-Compact 4mm Design: Miniaturized GL45 series profile makes it exceptionally simple to slot onto standard breadboards or densely packed PCBs.

• Reliable Protective Coating: Hermetically sealed with a durable epoxy resin topcoat to protect the internal track from moisture and oxidation.

• Wide Compatibility: Acts as a standard variable analog resistor, translating lux variations directly into measurable voltage drops for microcontrollers.

Common Applications

• STEM & Academic Electronics Kits: A popular tool for teaching students how to program interactive circuits, light detectors, and autonomous rovers.

• Automatic Light Control (ALC): Widely utilized to build solar-charging night lights, courtyard security lamps, and automatic street lighting relays.

• Industrial & Toy Control: Deployed inside smart toys, alarm systems, light barriers, and electronic optical shutters.
