LDR Electrical Characteristics Module

Product Code : SCL-EAE-11187

The LDR Electrical Characteristics Module is an electronics laboratory apparatus used to study how the resistance of a light-dependent resistor changes with illumination. It supports practical learning in photoresistive sensing, light intensity response, voltage divider circuits, resistance measurement, and low-voltage electronics experiments for schools, colleges, polytechnics, ITI/TVET centres, STEM labs, and procurement buyers.

Product Description

The LDR Electrical Characteristics Module from Lab Equipments Ambala is best positioned under Physics Lab / Electrical and Electronics / Sensor and Semiconductor Trainer. A dedicated product page with final product code, LDR type, resistance range, light-source arrangement, supply voltage, meter arrangement, terminals, circuit layout, protection, accessories, and documentation should be confirmed before publishing.

An LDR module helps learners observe the inverse relationship between light falling on the sensor and its electrical resistance. In a typical experiment, students vary illumination, measure resistance or output voltage, and record how the sensor behaves under dark, dim, and bright conditions. The exact measurement method should be verified from the supplied manual.

Key Features

• LDR characteristics study: supports practical observation of light-dependent resistance behaviour.
• Photoresistive sensor training: helps students understand how an LDR can be used in light-sensing and automatic switching circuits.
• Illumination response experiment: allows learners to compare sensor output under dark, dim, and bright conditions.
• Voltage divider learning: may support output-voltage study using the LDR with a fixed resistor; confirm final circuit design.
• Measurement-compatible setup: can be used with a multimeter, voltmeter, ammeter, resistance meter, or built-in display if supplied.
• Low-voltage electronics use: suitable for supervised electronics, physics, instrumentation, and STEM laboratory practicals.
• Specifications pending: LDR type, resistance range, light-source type, supply voltage, meter range, and accessories must be verified.

How to Use the LDR Electrical Characteristics Module

1. Place the module on a dry, stable laboratory bench away from uncontrolled glare where possible.
2. Confirm the LDR type, supply voltage, meter range, light-source arrangement, and circuit diagram before switching on.
3. Connect the LDR circuit, supply, and meter terminals according to the approved experiment layout.
4. Measure the LDR resistance or output voltage in a dark condition and record the reading.
5. Increase illumination gradually using the supplied or approved light source.
6. Record the corresponding resistance, voltage, or current readings at each illumination level.
7. Plot the required graph, such as resistance versus illumination or output voltage versus light condition, as specified in the manual.
8. Switch off the supply before changing connections, replacing the light source, or storing the module.

Safety note: Use the LDR Electrical Characteristics Module only with the confirmed low-voltage DC supply. Do not connect the module directly to mains supply. Avoid short circuits, observe correct polarity where applicable, do not exceed the confirmed sensor or meter rating, keep terminals dry, and conduct the experiment under instructor or laboratory technician supervision.

Care & Maintenance

• Keep the LDR window, light-source area, terminals, switches, panel markings, and connecting leads clean and dry.
• Inspect the sensor, sockets, wires, power input, light source, and meter terminals before each experiment.
• Do not expose the LDR, circuit board, or panel to excessive heat, moisture, high current, or incorrect supply voltage.
• Store the module in a dry, dust-controlled cabinet after laboratory use.

Frequently Asked Questions

What is an LDR Electrical Characteristics Module used for?

An LDR Electrical Characteristics Module is used to study how the resistance of a light-dependent resistor changes when the amount of light falling on it changes.

What readings are recorded in an LDR experiment?

Students typically record resistance, voltage, or current readings under different illumination levels such as dark, dim light, and bright light, depending on the supplied circuit diagram.

Does the module include a light source?

The light-source arrangement is not verified. Confirm whether the module includes a lamp, LED source, adjustable illumination unit, optical tube, or requires an external light source.

Does LDR resistance increase or decrease with light?

In a typical LDR, resistance decreases as light intensity increases and resistance increases in darker conditions. The exact measured range depends on the supplied LDR and experiment setup.

Can this module be connected directly to mains power?

No. The module should be used only with the confirmed low-voltage DC supply or approved adapter. Direct mains connection can damage the apparatus and create an electrical hazard.

What should be confirmed before ordering?

Confirm product code, LDR type, dark and illuminated resistance range, light-source type, supply voltage, meter arrangement, terminals, connecting leads, experiment manual, packing, and documentation.
