₹1,450.00
In StockAn Arduino-based smoke detection system using an MQ-3 sensor, buzzer, and LCD display to alert users when smoke or harmful gases are detected.
Description
This project is a Smoke Detection System using Arduino, an MQ-3 gas sensor, an LCD display, and a buzzer. The MQ-3 sensor detects smoke or harmful gases in the air, and when the concentration exceeds a predefined level, the buzzer starts buzzing to alert users. The LCD display shows real-time smoke levels and system status. This system can be used in homes, offices, industries, and fire safety applications to prevent accidents caused by smoke or gas leaks.
Features: Real-time Smoke Detection
Audible Alert
Compact and Low Power Consumption
Applications: Industrial Safety
Home and office safety
Smart Kitchen Monitoring
Public Safety and Emergency Systems

A Battery High-Low Monitor is an electronic circuit or device that detects and indicates the voltage level of a battery — whether it’s too high (overcharged), normal, or too low (discharged). It helps protect batteries from overcharging or deep discharge, which can damage the battery or reduce its lifespan.
These monitors often use comparators, voltage dividers, LED indicators, or microcontrollers to track and display battery status in real time.
