Product Description

The LDR Sensor 5mm (Light Dependent Resistor) is a widely used electronic component that changes its resistance according to the intensity of light falling on its surface. This pack of 3 pieces is ideal for experiments, prototyping, and learning applications where light sensing and automatic control are required. As the light level increases, the resistance of the LDR decreases, and when light intensity is low or in darkness, the resistance increases, making it perfect for light-based detection and switching circuits.

With its compact 5mm round head, this LDR sensor is easy to mount on PCBs, breadboards, and DIY modules. It is commonly used in automatic street light systems, light-activated alarms, solar trackers, brightness-controlled displays, and various Arduino and microcontroller-based projects. The sensor works efficiently with low power consumption and responds smoothly to changes in ambient light.

Designed for both beginners and professionals, the LDR sensor is an excellent choice for school science projects, college experiments, robotics, IoT, and DIY electronics. Its simple working principle helps students understand the basics of sensors and analog input behavior in electronic circuits. The pack of 3 provides flexibility for multiple projects or replacements during experimentation.

Applications:
Automatic lighting systems, light intensity measurement, Arduino and Raspberry Pi projects, robotics, solar tracking systems, alarm circuits, smart devices, and educational demonstrations.

Pack Includes:
3 × 5mm LDR (Light Dependent Resistor) Sensors
