LDR Resistor Board Manufacturer,Supplier and Exporter in India

Product Code : SCL-EI-10661

The LDR Resistor Board is an electronics laboratory component used for demonstrating how resistance changes with light intensity in school physics and sensor-circuit experiments. It is suitable for schools, colleges, STEM labs, electronics trainer boards, physics practical rooms, distributors, and institutional procurement buyers.

Product Description

The LDR resistor based product from Lab Glassware Manufacturer is best described as an LDR resistor board or light-dependent resistor base for low-voltage educational circuit demonstrations. An LDR, or light dependent resistor, changes its resistance when exposed to different light levels.

This apparatus helps students observe photoresistance, sensor action, voltage-divider output, automatic light-control circuits, and basic analogue electronics. It can be used with lamps, LEDs, meters, resistors, switches, relays, trainer boards, and safe low-voltage DC supplies where electrical ratings are verified. Exact resistance range, voltage rating, terminal design, board material, response time, and supplied accessories should be confirmed before final catalogue publication.

Key Features

• Light-dependent resistance demonstration: shows how LDR resistance changes under bright and dim light.
• Sensor-circuit learning: supports lessons on light sensors, voltage dividers, switching circuits, and automation.
• Educational board/base format: suitable for bench-top and trainer-board experiments where fitment is confirmed.
• Low-voltage circuit use: intended for school and college electronics practicals with safe power supplies.
• Capacity not applicable: this is an electronic component, not a liquid-volume product.
• Hands-on STEM value: useful for experiments on photoresistors, night-lamp circuits, and light-triggered devices.
• intended for school and college electronics practicals with safe power supplies.
• Capacity not applicable: this is an electronic component, not a liquid-volume product.
• Hands-on STEM value>Specification-dependent performance: dark resistance, light resistance, voltage limit, and response time must be verified.

How to Use the LDR Resistor Board

1. Confirm the voltage rating, terminal layout, and circuit diagram before use.
2. Place the board on a dry, stable laboratory bench.
3. Connect the LDR board into a low-voltage circuit as shown in the experiment method.
4. Use a meter to measure resistance or voltage output in normal room light.
5. Cover the LDR to reduce light and observe the change in reading.
6. Shine a lamp or torch on the LDR and compare the new reading.
7. Record resistance or voltage values at different light levels.
8. Switch off the power supply before changing connections.

Safety note: Use only with safe low-voltage supplies unless the product is specifically rated otherwise. Do not overload the LDR, connect it to mains electricity, expose it to excessive heat, or short circuit the power supply.

Care & Maintenance

• Store the LDR board dry and protected from dust, heat, and impact.
• Keep the sensor face clean for repeatable classroom readings.
• Do not scratch, press, or bend the LDR component.
• Remove from use if the board overheats, terminals loosen, or readings become unstable.

Frequently Asked Questions

What is an LDR Resistor Board used for?

An LDR Resistor Board is used to demonstrate how a light dependent resistor changes resistance when light intensity changes.

What does LDR mean?

LDR means light dependent resistor. It is also called a photoresistor because its resistance changes with light exposure.

What is the resistance range of this LDR?

The dark resistance and light resistance values are not confirmed. Add resistance range only after checking the product datasheet or supplier confirmation.

Can it be used for voltage-divider experiments?

Yes. An LDR can be used in a voltage-divider circuit to show how light intensity changes output voltage.

Does it require a power supply?

Power requirement depends on the experiment circuit. Use only the confirmed safe low-voltage supply for the final product configuration.

Is it suitable for school electronics labs?

Yes. It is suitable for supervised school and college electronics practicals on light sensors, resistance change, and basic automation circuits.
