Photoresistor is also known as photocell, or light dependent sensor (LDR) is a light controlled variable sensor. The photoresistor is a light sensitive device, its main function is indicating the presence or the absence of light. It is a resistor that changes its resistance value based on the tension of light. If the light intensity increases, the resistance decreases.
