Light detecting resistor
So in essence, the LDR is a light sensor capable of detecting the amount of light it’s subject to. ) As Figure 6 relay energised when light level drops below the level set by VR 1 (Relay. LDR (Light Dependent Resistor) as the name states is a special type of resistor that works on the photoconductivity principle means that resistance changes according to the intensity of light. True to its name, a photo-resistor is a device or we can say a … What is Light Dependent Resistor? An electronic component like LDR or light-dependent resistor is responsive to light. Connecting a Light Sensor to an Arduino. A LDR is a Light Detecting Resistor which changes resistance as light exposure level changes. 7v will activate the circuit.
