High Temperature Watertight Metal Housing LDR Light Sensor 5mm 12mm Cds Photocell
Description Of The Metal Housing LDR Light Sensor 5mm 12mm Cds Photocell
Light dependent resistor is made of semiconductor material. Also name LDR, photoconductor. The electric conductivity changs by the illuminance. The illuminance is more stronger, the value of the resistance will be more weaker. With this chareter, we can produce different size to satified different requirement. We have 5MM and 12MM series.

Advantages Of The Metal Housing LDR Light Sensor 5mm 12mm Cds Photocell
LDR’s are cheap and are readily available in many sizes and shapes. Practical LDRs are available in a variety of sizes and package styles, the most popular size having a face diameter of roughly 10 mm. They need very small power and voltage for its operation.
A Light Dependent Resistor (LDR) is also called a photoresistor or a cadmium sulfide (CdS) cell. It is also called a photoconductor. It is basically a photocell that works on the principle of photoconductivity. The passive component is basically a resistor whose resistance value decreases when the intensity of light decreases. This optoelectronic device is mostly used in light varying sensor circuit, and light and dark activated switching circuits. Some of its applications include camera light meters, street lights, clock radios, light beam alarms, reflective smoke alarms, and outdoor clocks.
FAQ
| What is LDR how it operates? | The working principle of an LDR is photoconductivity, which is nothing but an optical phenomenon. When the light is absorbed by the material then the conductivity of the material enhances. When the light falls on the LDR, then the electrons in the valence band of the material are eager to the conduction band. |
| What is the LDR sensor? | What is an LDR (Light Dependent Resistor)? An LDR is a component that has a (variable) resistance that changes with the light intensity that falls upon it. This allows them to be used in light sensing circuits. Light Dependent Resistors (LDR) are also called photoresistors. |
| What is LDR and its function? | Photo resistors, also known as light dependent resistors (LDR), are light sensitive devices most often used to indicate the presence or absence of light, or to measure the light intensity. ... LDRs have a sensitivity that varies with the wavelength of the light applied and are nonlinear devices. |
| What is LDR in light? | A photoresistor (also known as a 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. |
| Is LDR a sensor? | The sensor that can be used to detect light is an LDR. ... The LDR gives out an analog voltage when connected to VCC (5V), which varies in magnitude in direct proportion to the input light intensity on it. |
| How LDR is used in street lights? | Street lights are designed to switch on automatically when it is dark and switch off when there is light so as to save energy. ... It is a resistor with resistance that changes according to the amount of light falling on it. When the LDR is in the dark, its resistance is very large, typically in the M range. |
