LDR sensor

Click to Try This Simulation

In this simulation, students explore how an LDR (Light Dependent Resistor) Sensor detects changes in light intensity. They can connect the sensor to a power supply and an LED module, then observe how the LED responds as the light level changes. This activity introduces the basics of light sensing and demonstrates how LDR sensors are used in automatic lighting and smart electronic systems.
