The core objective of the IoT-based Heart Rate Monitor for Pilots project is to enhance flight safety and reduce the likelihood of pilots experiencing heart-related issues during aviation operations. This system comprises two main components: a transmitting circuit integrated into the pilot's equipment and a receiver circuit that is under the supervision of a responsible guardian or flight supervisor. Central to this heart rate monitoring system is a highly sensitive heartbeat sensor that continually tracks the pilot's heart rate. Real-time heart rate data is then transmitted to a digital display screen. The transmitting circuit is equipped with an advanced AVR family microcontroller, which is powered by a dependable 12V electrical source. Conversely, the receiving circuit incorporates another AVR family microcontroller fitted with an RF receiver. Importantly, the receiver circuit is equipped with both LED indicators and a buzzer to promptly notify the guardian when the pilot's heart rate deviates from the normal range. The continuous heart rate monitoring and seamless communication between these circuits establish an effective early warning system. This system significantly bolsters pilot safety during flights, ultimately ensuring the well-being of both pilots and passengers. Furthermore, the success of this project serves as a testament to the potential of IoT-based solutions in revolutionizing aviation safety practices. In summary, the IoT-based Heart Rate Monitor for pilots represents a pivotal advancement in aviation safety technology. Its role in detecting potential heart failures and safeguarding the lives of pilots and passengers is invaluable. By delivering a dependable and efficient early warning system, this life-saving project has become an indispensable asset in the pursuit of safer and more secure flight operations.
