Working Principle Characteristics Construction of a Photocell Applications What Working principle of LDR A light dependent resistor works on the principle of photo conductivity. Applications ... LDR SUNROM #3190. They are used when there is a need to detect absences or presences of light like in a camera light meter. Working principle of LDR A light dependent resistor works on the principle of photo conductivity. 2.3 Scope Of Problem The main problem is the automatic switch system with comparator Op-Amp and LDR Censor (Light Dependent Resistor Censor). An LDR or light dependent resistor is also known as photo resistor, photocell, photoconductor.It is a one type of resistor whose resistance varies depending on the amount of light falling on its surface. The resistance of a photoresistor decreases with increasing incident light intensity; in other words, it exhibits photoconductivity. What is a Light Dependent Resistor or a Photo Resistor? Light dependent resistors are simple and low cost devices. Providing knowledge about applications as a comparator Op-Amp . An LDR (light dependent resistor) is a component that has a (variable) resistance that changes with the light intensity that falls upon it. They are often used as light sensors. A photoresistor (or light-dependent resistor, LDR, or photoconductivecell) is a light-controlled variable resistor. ";s:7:"keyword";s:19:"applications of ldr";s:7:"expired";i:-1;}
