WebThe Light Dependent Resistor. The NTC Thermistor. 1. The Light Dependent Resistor. LDRs: what are they made from and how do they work? 2. The NTC Thermistor. This … A photoresistor (also known as a photocell, or light-dependent resistor, LDR, or photo-conductive cell) is a passive component that decreases resistance with respect to receiving luminosity (light) on the component's sensitive surface. The resistance of a photoresistor decreases with increase in incident light intensity; in other words, it exhibits photoconductivity. A photoresistor can be applied in l…
