Abstract —
This paper presents the design and implementation of a Smart Household Management System (SHMS), an IoT based platform that integrates real-time environmental sensing, safety alerting, energy monitoring, and household productivity management into a unified web interface. The system employs an ESP32 microcontroller interfaced with a DHT11 temperature and humidity sensor, an MQ-2 gas concentration sensor, and a voltage sensing module. Sensor data is published over a local Wi-Fi network via HTTP and consumed by a Python Flask backend that aggregates, enriches, and exposes the data through RESTful APIs. A responsive single-page web dashboard renders live readings, sparkline trend visualizations, safety alerts, task management, and expense tracking. Threshold-based automated safety alerting triggers critical notifications when gas concentrations exceed 9,000 PPM or ambient temperature surpasses 45°C. Experimental results demonstrate stable real-time operation with a 3- second data refresh cycle, effective noise reduction through ADC sample averaging, and a reliable browser based interface for household monitoring. This work demonstrates an accessible, low-cost approach to smart home automation suitable for residential environments, with clear pathways for enhancement in security, persistence, and scalability.
