A smart streetlight system designed and programmed by Grade 6 students using LDR (Light Dependent Resistor) sensors and basic coding through mBlock, to promote energy efficiency and sustainability. The project works by detecting light intensity: when natural light decreases, the LDR sensor signals the system to automatically turn the streetlights on, and when daylight returns, the lights switch off. This reduces unnecessary energy consumption and promotes responsible resource use.
Through this hands-on activity, students gained practical experience in basic electronics, sensor integration, and block-based coding. They learned how technology can be used to solve real-world problems, particularly in the context of smart cities and environmental conservation. The project also encouraged teamwork, critical thinking, and creativity, while reinforcing the importance of innovative solutions that contribute to a greener and more sustainable future.
