Light Dependent Resistors: What Are Their Applications and Types?

Posted by wang meihong on October 26, 2023 at 9:22pm in Blogs

The majority of outdoor lights, street lights, and many of your indoor appliances are typically maintained and operated manually in many instances, just like the outdoor lights, street lights, and a few home appliances. It isn’t just risky; it results in power wastage through personal negligence or rare circumstances for the control of electrical appliances to be turned on and off. By working with light sensors, we can use the light dependent sensor to automatically switch the system off based on the intensity of daylight.

There are a number of applications that can be applied to a light dependent resistor, both theoretically and practically. In this article, we will discuss briefly what a light dependent resistor is, how it is made, and what its applications are.

What is a Light Dependent Resistor?

A Light Dependent Resistor (LDR), also known as a photoresistor, is a type of passive electronic component that exhibits a change in electrical resistance when exposed to light. The resistance of an LDR decreases as the intensity of incident light on it increases and, conversely, increases as the light intensity decreases. This property makes LDRs useful in a variety of applications where you want to detect or measure light levels.

LDRs are typically made of a semiconductor material, often cadmium sulfide (CdS) or lead sulfide (PbS), that is sensitive to light. When photons from light strike the semiconductor, they create electron-hole pairs, which in turn affect the material's conductivity. In well-lit conditions, there are more electron-hole pairs, leading to lower resistance and better electrical conductivity. In darkness, there are fewer electron-hole pairs, resulting in higher resistance and reduced conductivity.

Light Dependent Resistors: How Do They Work?

Light dependent resistors work based on the principle of photoconductivity. When light strikes or falls on a surface, the material conductivity reduces, and electrons in the valence band are excited by the conduction band. Also, the photons present in this incident light must have a higher energy than the band gap of the semiconductor material.

Furthermore, this will make the electrons jump from their valence band to the conduction band. Light is an essential component of all these devices. Light dependent resistors decrease in resistance when it falls or drops, which causes them to increase in resistance when it is dark. LDRs have high resistance when placed in dark areas, and if they are placed in light, they have a lower resistance.

What Are the Different Types of the Light Dependent Resistor?

Light Dependent Resistors (LDRs) are categorized based on the materials from which they are constructed.

Intrinsic Light Dependent Resistors

Intrinsic LDRs are typically composed of pure semiconductor materials like germanium or silicon. When incident light strikes an intrinsic LDR, it excites electrons from the valence band to the conduction band, resulting in an increase in charge carriers.

Extrinsic Light Dependent Resistors

Extrinsic LDRs are intentionally doped with various impurities. These impurities introduce new energy bands located above the valence band. These new bands are then populated with electrons, reducing the bandgap, and requiring only a small amount of energy to move the electrons. Extrinsic LDRs are particularly well-suited for capturing long-wavelength light.

Describing the Circuit Diagram of the LDR – Light Dependent Resistor

In the circuit diagram of a light-dependent resistor (LDR), when the ambient light intensity is low, the LDR exhibits high resistance. This results in the interruption of current flow to the base terminal of the transistor, preventing the LED from illuminating. Conversely, when the light intensity on the LDR is high, its resistance decreases. As a result, current flows to the base of the first transistor and subsequently to the second transistor, causing the LED to emit light. In this scenario, the resistance can be adjusted using a preset resistor to either decrease or increase it as needed.

What Are the Applications of the Light Dependent Resistor?

Light-dependent resistors are characterized by their affordability and straightforward design, often serving as light sensors. They find practical use in scenarios where the presence or absence of light needs to be monitored, such as in alarm clocks and burglar alarm circuits.

Additionally, LDRs play a prominent role in a variety of electronic and electrical projects.
Electronic Eye-Controlled Security System

In this security system, an electronic eye governs its operation through a photosensitive arrangement. The system employs a 14-stage ripple binary counter to gauge light intensity via a light-dependent resistor (LDR). The system's output triggers both a buzzer and a relay to initiate the necessary action.

This project relies on the light-dependent resistor. When light falls upon the LDR sensor, its resistance decreases, activating the alarm to alert or notify the user. This project is particularly beneficial for enhancing security in lockers, cash boxes typically found in banks, jewel shops, and shopping malls.

Street Light Intensity Control (LDR-Based)

Highway lighting typically utilizes HID lamps, which consume substantial energy. This project employs LEDs (light-emitting diodes) as a more efficient light source to address the drawbacks associated with HID lamps.

Sunset-to-Sunrise Lighting Switch

The lighting switch designed for operation from sunset to sunrise is aimed at regulating the illumination based on LDR sensors. The LDR sensor's resistance changes when the light intensity falling on it fluctuates. The sensor's output is directed to an IC 555 timer configured in bistable mode.

Moreover, the IC 555's output is employed to control the load via a TRIAC. Consequently, this circuit facilitates the activation of the load during sunset and its automatic deactivation at sunrise.

Conclusion

In conclusion, this comprehensive article has shed light on the Light Dependent Resistor (LDR) and its various aspects, from its fundamental principles to its practical applications. It has unveiled the significance of LDRs in revolutionizing the control of light in both indoor and outdoor settings.

By exploring LDRs' potential applications, including security systems and energy-efficient lighting solutions, we've highlighted their invaluable role in enhancing safety, energy conservation, and automation. These versatile devices have empowered us to harness the power of light effectively.

We trust that the insights provided here have equipped you with a solid understanding of LDRs, enabling you to appreciate their contributions to various fields, from electronics and security to environmental control.
