LDR Circuit Board
Product Code : JA-EE-7541
The LDR Circuit Board (SKU JA-EE-7541) is a simple circuit board carrying a light dependent resistor for light-sensing experiments in school electricity and electronics lessons. On this LDR circuit board the sensor has a resistance of approximately 250 ohms in normal room conditions, rising as the light is reduced, so students can see resistance change with light level and use it in simple sensing circuits. JaincoLab supplies it with matching LED boards.
Specifications
The LDR Circuit Board mounts a light dependent resistor on a simple board; its resistance is about 250 ohms in normal room conditions and increases as the light falling on it is reduced, and the dark resistance, board format and connections are confirmed on the quotation.

Applications of the LDR circuit board
The board is used to show how an LDR responds to light, first by measuring its resistance in room light and when shaded, and then by building light-sensing circuits that switch or dim an LED or lamp as the light level changes.
- Measuring LDR resistance in room light and when shaded
- Light-dependent brightness of an LED or lamp in series
- Light or dark alarm circuits with the LED boards
- Potential divider sensing circuits in electronics lessons
