Light Dependent Resistor LDR 3mm حساس ضوئي

This Light Dependent Resistor (LDR) with a 3mm sensing surface detects ambient light intensity by varying its electrical resistance in response to light exposure. Its compact form factor and focused sensing area make it suitable for projects where space is limited and precise light detection is required.

• 3mm diameter sensing surface for a focused and accurate light detection area.
• High sensitivity with a rapid response to changing light conditions.
• Wide operating range suitable for dim to bright environments.
• Low dark resistance to minimize current leakage when not illuminated.
• Durable construction designed to withstand typical environmental wear and tear.

Compared to standard LDRs, this 3mm sensor provides enhanced responsiveness and a smaller footprint, facilitating integration into compact electronic assemblies and hobby circuits. Its lower dark resistance improves overall circuit efficiency by reducing energy loss when the sensor is in low-light conditions.

Built using photoconductive materials that change resistance quickly with light level variations, the sensor delivers consistent performance for lighting control, alarm systems, automation, and other applications that require dependable ambient light sensing. The compact 3mm sensing surface helps target detection to specific areas while preserving versatility for general use.
