Description

Light Dependent Resistor (LDR) sensor:

• Size: 5 mm in diameter (standard size for many LDR sensors).
• Resistance Range: LDRs have a wide resistance range. In darkness, their resistance is usually in the megaohm (MΩ) range, and in bright light, it can drop to several hundred ohms (Ω).
• Operating Voltage: They are designed to operate at low voltages, often between 3V to 5V, making them suitable for various electronic projects and circuits.
• Spectral Range: LDRs are sensitive to a broad range of wavelengths in the visible spectrum, typically covering most of the visible light range.
• Response Time: The response time of an LDR can vary but is generally in the millisecond range.
• Dark Resistance (Rd): This is the resistance of the LDR in total darkness, usually specified in megaohms.
• Illuminated Resistance (Ri): This is the resistance of the LDR when exposed to bright light, specified in ohms.
• Sensitivity: It indicates how much the resistance changes concerning the intensity of light. It is usually given in terms of resistance change per unit of illuminance (e.g., ohms per lux).
