Simple Circuit Module Light Dependent Resistor Board
Simple Circuit Module Light Dependent Resistor Board (Product Code: SLE/PHY/79) is a board-mounted light dependent resistor from the Simple Circuit Modules range, used to add a light sensor to school electricity circuits. In normal room conditions its resistance is approximately 250 ohms, and shading it raises the resistance, so students can watch light level control a circuit. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

What Is the LDR Circuit Module Used For?
Placed in series with a lamp or LED module and a few cells, the LDR board makes the light output change as students cover and uncover it, a direct way to show that resistance controls current. With a multimeter across it, groups can record resistance against the distance from a lamp and plot a graph, a common activity in OPTO electronics experiment kit lessons.
Because the resistor is already mounted, there are no fragile leads to bend and the module drops into a circuit alongside the other boards in the range. Take readings away from direct sunlight so results repeat from one group to the next, and compare the board with the bare component when explaining how sensors are built into real products.
What to Specify When Ordering
- Number of LDR boards needed
- Other Simple Circuit Modules to go with them, such as LED, lamp or switch boards
- Whether you need the fully covered resistance value confirmed before ordering
Supplier

Frequently Asked Questions
What is the resistance of the LDR board in normal light?
The Simple Circuit Module Light Dependent Resistor Board has a resistance of approximately 250 ohms in normal room conditions. The value rises as the resistor is shaded and falls in brighter light, which is how it senses light level in a circuit.
What is the LDR board's resistance when fully covered?
The listing for the Simple Circuit Module Light Dependent Resistor Board does not give a reliable covered value, so we do not quote one here. Ask us through the contact page and we will confirm the dark resistance of the boards currently supplied.
How is the LDR board used with other Simple Circuit Modules?
The Simple Circuit Module Light Dependent Resistor Board connects in series with lamp or LED boards and a cell supply, so shading the LDR dims the indicator. Adding a switch module lets students control the whole light-sensing circuit.
How is the board different from a loose LDR?
The Simple Circuit Module Light Dependent Resistor Board carries the LDR ready-mounted, so there are no thin leads to bend or break and it fits straight into module circuits. A loose LDR suits soldered projects and breadboards instead.
Who supplies the Simple Circuit Module Light Dependent Resistor Board?
The Simple Circuit Module Light Dependent Resistor Board is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, India, together with the other boards in the Simple Circuit Modules range for schools and dealers.
Can the LDR board be ordered for a whole class?
Yes, the Simple Circuit Module Light Dependent Resistor Board can be ordered in class quantities with matching LED, lamp and switch modules. Send the quantities and delivery location through the enquiry cart or contact page to receive a quotation.
