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.
Jul 18, 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.
Oct 26, 2023 · Light Dependent Resistors (LDRs), also known as photoresistors, are a crucial component in the world of electronic circuits. These components exhibit photoconductivity, which essentially means their resistance changes based on the intensity of light they are exposed to.
Jun 18, 2023 · A light-dependent resistor (LDR) is a passive electronic component that changes its resistance according to the intensity of light that falls on its surface. LDRs are also known as photoresistors, photocells, or photoconductors.
Light Dependent Resistor (Photoresistor) Definition. Photoresistors are light sensitive resistors whose resistance decreases as the intensity of light they are exposed to increases. Characteristics. Types of photoresistors and working mechanisms. Based on the materials used, photo resistors can be divided into two types: intrinsic and extrinsic.

Aug 15, 2023 · LDR (Light Dependent Resistor) as the name states is a special type of resistor that works on the photoconductivity principle means that resistance changes according to the intensity of light. Its resistance decreases with an increase in the intensity of light. It is often used as a light sensor, light meter, Automatic street light, and in ...
Jun 11, 2023 · A Light Dependent Resistor (LDR), also known as a photoresistor, is a type of resistor whose resistance changes with the intensity of light it is exposed to. As the light level increases, the resistance of the LDR decreases, allowing more current to flow through it.
