The "Smart Jacket for Coal Miners" represents a significant advancement in safety technology tailored specifically for the challenging conditions of coal mining. By integrating components such as a robust battery, DHT-11 sensor for environmental monitoring, Arduino UNO for centralized control, MQ-05 gas sensor for detecting hazardous gases, MAX 30100 pulse oximeter for health monitoring, buzzer for audible alerts, and an LCD display for real-time feedback, this innovative wearable aims to enhance safety and operational efficiency. The jacket's battery ensures continuous operation in remote and demanding environments, powering a suite of sensors that monitor temperature, humidity, gas levels, and vital signs crucial for miners' safety. The Arduino UNO processes data from these sensors, triggering alerts through the buzzer and displaying critical information on the LCD display. By providing early warnings of hazardous conditions such as high gas levels or unsafe environmental parameters, the Smart Jacket empowers miners with timely information to make informed decisions and take necessary precautions. This technology not only mitigates risks associated with coal mining but also improves response times during emergencies, ultimately fostering a safer working environment for coal miners.            

The main objectives of the project are:  

• Enhance safety by monitoring environmental conditions and detecting hazardous gases.
• Provide real-time health monitoring of miners to prevent health-related incidents.
• Issue immediate alerts and warnings to miners in case of dangerous situations.
• Improve overall operational efficiency and emergency response capabilities in coal mining environments.
