Una fotorresistencia, fotorresistor o LDR (por su nombre en inglés Light-dependent resistor) es una resistencia cuyo valor varía en función de la cantidad de luz incidente. En concreto, cuanta más luz llegue a la fotorresistencia, menor será su resistencia.
18 de jul. de 2019 · 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. When the light falls on the resistor, then the resistance changes.
El sensor LDR, también conocido como sensor de resistencia dependiente de la luz, es un componente electrónico utilizado para medir la intensidad de la luz en un entorno determinado. Este sensor es ampliamente utilizado en diversas aplicaciones, como sistemas de iluminación automática, cámaras fotográficas, sistemas de seguridad y control ...
18 de jun. de 2023 · The spectral response curve shows how the resistance changes with different wavelengths for a given LDR. Response time: The response time is the time taken by an LDR to change its resistance when exposed to or removed from light. The response time consists of two components: rise time and decay time.

Can someone tell me (or link me) the response curve of an LDR. I don't mean the frequency response, just the intensity response; is it linear, or logarithmic? ldr. Share.

A photoresistor (also known as a photocell, or light-dependent resistor, LDR, or photo-conductive cell) is a passive component that decreases in resistance as a result of increasing luminosity (light) on its sensitive surface, in other words, it exhibits photoconductivity.
For the digital ON-OFF applications such as flame detectors, LDRs with steep slopes to their resistance versus light intensity curves are appropriate. For analog or measurement types of applications such as exposure controls for cameras, LDRs with shallow slopes may be better suited.
