5mm Light Dependent Resistor (LDR) Sensor
The 5mm Light Dependent Resistor (LDR) Sensor is a compact, highly responsive photoresistor ideal for use in Arduino, Raspberry Pi, IoT systems, and smart lighting projects. It changes its resistance based on ambient light levels, making it perfect for building automatic lighting, security systems, solar trackers, and energy-saving devices.
With a working voltage of 3.3V to 5V, this sensor is easy to integrate into any microcontroller-based system. It offers quick response time (typically under 20ms), ensuring real-time adaptation to changing light conditions.
Whether you’re working on DIY home automation, streetlight automation, or educational electronics kits, this LDR is a reliable component for detecting daylight or artificial light intensity.
