What is LDR Sensor – Working, Application and All About It

The LDR sensor, which stands for light-dependent resistor, is a remarkable device that plays a crucial role in detecting light intensity. Essentially, the LDR sensor works by varying its resistance in response to changes in light, making it invaluable in applications like automatic lighting control and security systems. The question of what is an LDR sensor? is best answered by understanding its functionality and versatility. The use of LDR sensors extends from simple DIY projects to sophisticated industrial applications. LDR sensors are like light detectives that change their behavior when light levels change. They’re super useful for things like making lights turn on automatically or keeping an eye on security. Whether you’re just starting out with DIY projects or working on big industrial setups, LDR sensors can easily fit into your circuit using a breadboard.
