Abstract
The IoT-Based Smart Helmet for Soldiers is developed to detect hazardous gases in real-time and trigger instant alerts. It uses MQ7 and MQ135 sensors to measure carbon monoxide and air quality, with DHT11 and IR sensors for environmental monitoring. Sensor data is displayed on an LCD and uploaded to the ThingSpeak IoT cloud via ESP8266. If unsafe gas levels are detected, a buzzer alarm activates, ensuring quick response and improved safety in defense and industrial applications.

Objectives
1. Detect hazardous gases in real-time
2. Monitor environmental data
3. Trigger buzzer + cloud logging

Components required
1. Arduino UNO
2. MQ7 Sensor
3. MQ135 Sensor
4. DHT11 Sensor
5. IR Sensor
6. 16×2 LCD
7. ESP8266 Wi-Fi
8. Buzzer 5V

Methodology
The IoT-based smart helmet works by integrating gas sensors (MQ7, MQ135) with an Arduino UNO that continuously monitors toxic gases like carbon monoxide and harmful air pollutants. A DHT11 sensor measures environmental temperature and humidity, while an IR sensor assists in condition detection. The data is displayed on a 16×2 LCD and simultaneously uploaded to the ThingSpeak IoT cloud via the ESP8266 Wi-Fi module. When gas levels cross safe limits, the Arduino activates a buzzer alert, providing instant feedback to the soldier in hazardous areas.
