How a photoresistor works
Web3 de jan. de 2024 · How does the photoresistor work? 1. Working principle. The working principle of the photoresistor is based on the internal photoelectric effect. Photosensitive resistors are formed by mounting electrode leads at both ends of the semiconductor photosensitive material and encapsulating them in a tube case with a transparent window. WebAn LDR or photoresistor is made up of a high resistance semiconductor having no P-N junction. Hence an LDR or photoresistor is a passive component. One such …
