Development of a Microcontroller-Based Power Monitoring System for Comparative Efficiency Analysis of LED, CFL, and Incandescent Lamps
This study developed and evaluated an Arduino Uno R3-based power-monitoring prototype using ACS712 and ZMPT101B sensors to compare 450-lumen LED, CFL, and incandescent lamps. Each lamp underwent ten trials, with twelve samples per trial. Sensor readings were validated against a digital multimeter. Mean apparent power w...
