5mm LDR

Specification

5 mm LDR

Voltage : 3V to 5V

Description 

Light Dependent Resistor (LDR) sensor:

1. Size: 5 mm in diameter (standard size for many LDR sensors).

2. 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).

3. Operating Voltage: They are designed to operate at low voltages, often between 3V to 5V, making them suitable for various electronic projects and circuits.

4. Spectral Range: LDRs are sensitive to a broad range of wavelengths in the visible spectrum, typically covering most of the visible light range.

5. Response Time: The response time of an LDR can vary but is generally in the millisecond range.

6. Dark Resistance (Rd): This is the resistance of the LDR in total darkness, usually specified in megaohms.

7. Illuminated Resistance (Ri): This is the resistance of the LDR when exposed to bright light, specified in ohms.

8. 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).

Remember that the specific specifications of a 5 mm LDR may vary depending on the manufacturer and model. For accurate and up-to-date information, you should consult the datasheet or product documentation from the manufacturer or contact electronic component suppliers.
