This document describes a smoke alert system for dye industries using IoT technology. The system uses an Arduino Uno microcontroller connected to an MQ2 smoke sensor and buzzer. When smoke is detected above a threshold level, the buzzer is activated to alert users. The Arduino also interfaces with an LCD display to show the system status and whether smoke or overheating is detected. The goal is to quickly detect fires or excessive smoke in dye industries to minimize property damage and safety risks.
