WebMar 25, 2024 · Photoconductive cells feature a lens on their top surface, which works to … 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…
WebMar 16, 2024 · A photodiode array detector consists of an array or series of adjacent photosensitive diodes (Figure 1.3 C. 16 ). Radiation striking a diode causes a charge buildup that is proportional to the intensity of the radiation. The individual members of the array are known as pixels and are quite small in size. Since many pixels or array elements can ... WebAug 14, 2024 · Photodiode used as a light sensor. As the current in it is directly proportional to the intensity of light thus also used to measure the intensity of light. We can use the photodiode in smoke detectors to sense smoke and fire. Photodiode coupled with led to make optoisolators and optocouplers. Used in a solar panel as solar cells.
