Electricity had become one of the most essentials in life. The need for electricity keeps increasing. It has become a challenge to maintain this service evenly to everyone around the world. The high ...

Automatic Anchor Light Circuit and Working The circuit described here (refer to Fig. 3) lets you control an electromagnetic relay so that it turns on a white LED light when the preset light level is ...

It's ideal for building automatic night lights or light-sensitive systems. Light-Activated LED using LDR and Arduino This Arduino project uses a Light Dependent Resistor (LDR) to automatically turn on ...

This project presents a hybrid energy harvesting system using solar panels and piezoelectric transducers to power a smart street lighting system. Designed for sustainable urban infrastructure, it ...

Urbanization and modernization have significantly increased traffic congestion, creating challenges for daily commuters and emergency services. The traditional traffic light system, which runs on a ...

Light-dependent resistor (LDR) The resistance of a LDR depends on light intensity. At low light levels, the LDR has a high resistance. As the light intensity increases, the resistance decreases. A LDR ...

Most reported photocatalytic systems that primarily rely on the absorption of ultraviolet (UV) and short visible light irradiation face significant limitations, including shallow penetration in ...
