The LDR sensor, or light-dependent resistor, is a handy device that detects light levels. It changes its resistance based on the amount of light it receives, making it great for automatic lights and security systems. So, what is an LDR sensor? Simply put, it’s like a light detective that reacts when light levels change. These sensors are useful for turning lights on or monitoring security. Whether new to DIY projects or working on big industrial setups, LDR sensors can easily fit into your circuits with a breadboard. Despite its advanced working mechanism, the LDR sensor price remains affordable, offering a cost-effective solution for light detection needs. The LDR sensor stands for Light Dependent Resistor. It works by changing resistance based on the light intensity. The LDR sensor working in the automated lighting system efficiently adjusts the brightness based on the ambient light conditions. When exploring light-sensitive circuits, one might ask, “What is the use of an LDR sensor?” This question helps to understand how it adjusts the brightness of lights automatically.
