Abstract
This research project implements and designs an IoT-based smart grid and monitoring system. The main goal of this technology is energy efficiency. The system manages LCD panel output, voltage, and current sensor input using an Arduino Uno microcontroller board as the main processing unit. The design uses a ZMPT101B voltage sensor and an ACS712 current sensor. Sensor data is shown on a 16 x 2-character LCD screen in real time. When current and voltage thresholds are surpassed, MQTT messages are sent to the user's phone. The system is efficient since it can connect to the internet and communicate with the MQTT broker. This is done using the NodeMCU Wi-Fi module. The suggested technology reduces energy inefficiency and allows real-time energy monitoring. The experimental findings show that the proposed energy management system works and has several applications.
