5MM LDR (5 PCS)

The 5mm LDR (Light Dependent Resistor) is a light-sensitive component that changes resistance based on ambient light intensity. When exposed to light, its resistance decreases, allowing more current to flow. It is widely used in automatic lighting systems, solar tracking devices, and security alarms. The LDR provides a simple and cost-effective way to measure light levels without complex circuitry. It is commonly used in night lamps, outdoor garden lights, and photography exposure control. The LDR is highly durable and can operate in both AC and DC circuits. It is often integrated with microcontrollers like Arduino for smart automation projects. The response time of the LDR varies depending on the light intensity and wavelength.
