IOT Based Smart Helmet

This project presents the design and development of a smart helmet equipped with gas, temperature, and humidity sensors, along with a microcontroller unit and a 16x2 display. The helmet is designed to be worn by miners and workers in other industrial settings to provide real-time data on their immediate environment. The helmet's microcontroller unit, based on the NodeMCU, collects data from the sensors and displays it on the helmet's display, allowing the user to monitor the conditions around them. In addition to local monitoring, the helmet's data can be transmitted to a web or mobile application, providing remote monitoring and alerting features. The application can generate alert signals on a buzzer in response to high concentrations of harmful gases, ensuring that the user is aware of potential hazards in their surroundings. The results of the project demonstrate the feasibility of a low-cost, wearable device that can improve safety and awareness for workers in hazardous environments. The smart helmet is versatile, and its design can be adapted to different industrial applications. This project lays the foundation for future research and development in the field of wearable technology for occupational safety. This project aims to develop a smart helmet that can be used for miners and various other industrial uses. The helmet is equipped with a gas sensor, a DHT temperature and humidity sensor, and a 16x2 display. The main microcontroller unit used in this project is NodeMCU, which facilitates the display of data on a web or mobile app. The web and mobile app also have the functionality to generate alert signals on a buzzer. The gas sensor installed in the helmet can detect high concentrations of harmful gas and trigger the buzzer to generate an alert signal. The helmet can help improve the safety of miners and other industrial workers by providing real-time data on gas levels, temperature, and humidity. This project can be further developed to incorporate more sensors and features to enhance its functionality and application in various industries.
