If you’ve ever wondered how street lights automatically turn on when night falls, the answer often lies in the LDR & Relay-based Street Light Control system. In this blog, we’ll break down how this technology works and why it’s such a valuable component in modern lighting systems.
What is LDR & Relay Street Light Control?
LDR stands for Light Dependent Resistor, a sensor that detects changes in light intensity. When darkness falls, the LDR stops conducting, triggering a relay to turn on the street light. Conversely, when light returns, the LDR starts conducting again, switching the light off.
The LM393 IC acts as a comparator, ensuring the circuit operates efficiently in varying light conditions. This technology is not only effective but also economical, reducing the need for manual intervention.
Why is it Important?
This system is particularly useful in regions where street lighting is critical for safety and energy efficiency. By automating the light control, it reduces electricity consumption, especially during periods of low light intensity.
Whether for residential streets, remote areas, or urban settings, the LDR & Relay-based Street Light Control ensures reliable performance. It’s a key component in smart cities aiming for energy efficiency and automation.
