Photoresistor Sensor

The Photoresistor Sensor, also known as a light-dependent resistor (LDR), detects light levels by changing its resistance based on the intensity of light falling on it. As the light intensity increases, the resistance decreases, and vice versa. This analog sensor provides a variable resistance output that can be read by analog-to-digital converters in microcontrollers like Arduino, making it suitable for light-sensing applications. Ideal for projects such as automatic lighting systems, light level detection, and solar tracking, the Photoresistor Sensor offers a straightforward and effective way to integrate light measurement into your electronics projects.
