Buy an Advanced Photonix LDR sensor. Features 20MΩ dark resistance, 60mW power rating, 200V voltage for light control circuits.
The Advanced Photonix Light Dependent Resistor (LDR) is an essential electronic component whose electrical resistance varies with the intensity of incident light. This key property makes it a fundamental sensor for countless applications where light detection and control are required, offering a simple, robust, and cost-effective solution.
Constructed with high-quality materials, this two-pin device is designed for reliable performance across its specified operational parameters. Its resistance changes dramatically from a high value in darkness to a much lower value when illuminated, enabling it to act as a precise analogue sensor in light-sensitive circuits. This characteristic allows for the creation of automatic lighting systems, dusk-to-dawn controllers, and light-level monitoring devices.
The LDR features a voltage rating of 200V and a power rating of 60mW, ensuring safe operation within a wide range of electronic circuits. It operates within a defined temperature range, maintaining stable performance for consistent results. Its compact physical dimensions make it easy to integrate into circuit boards or prototyping setups without requiring excessive space. As a passive component, it requires no complex interfacing, making it an ideal choice for both hobbyist projects and professional electronic designs where dependable light sensing is paramount.
