Light sensor (LDR)

The Light Dependent Resistor (LDR) is an analog sensor low-cost that changes its resistance according to the intensity of ambient light. It features high sensitivity to light variations and can be easily connected with controllers like Arduino, ESP32, and Raspberry Pi. Resistance decreases with increasing light intensity, allowing simple measurement of the lighting level in the environment. Thanks to its compact design and ease of use, the LDR is an ideal option for light sensing applications, automatic lighting control, and educational electronics projects. Features: Detects light intensity through variable resistance Operating voltage: from 3.3V to 5V Easy analog interface with controllers Compact and low-cost design Applications: light-activated switches, ambient light monitoring, educational electronics, and IoT projects
