LDR Light Sensor Module (Photoresistor Module) for Arduino [Pack of 2]

📌 Product Name:

📝 Product Description:
The LDR (Light Dependent Resistor) Module is used to detect light intensity by changing its resistance according to surrounding light levels. In bright light, its resistance decreases, and in darkness, its resistance increases. This module converts light changes into electrical signals, making it ideal for automatic lighting, smart devices, and DIY electronics projects. It is simple to use and perfect for beginners and students.
