Gas Safety Monitoring System Using IOT

This project is a Gas Safety Monitoring System that continuously detects air quality, gas leakage, temperature, and humidity using MQ-135, MQ-06, and DHT11 sensors. The readings are displayed on a 0.96-inch OLED screen, and an alert is triggered using a buzzer when dangerous levels are detected.

🚀 Features

• Gas Detection: MQ-135 (Air Quality) & MQ-06 (LPG, Butane, Methane)
• Temperature & Humidity Monitoring: DHT11 Sensor
• Visual Alerts: OLED display with animated progress bars
• Audio Alert: Buzzer activation for hazardous conditions

🛠️ Components Used

• ESP8266 NodeMCU / Arduino Uno
• MQ-135 Gas Sensor
• MQ-06 Gas Sensor
• DHT11 Temperature & Humidity Sensor
• 0.96-inch OLED Display (SSD1306, I2C)
• Buzzer
• Jumper Wires & Breadboard

🔧 Circuit Connection
