Smart Pitot Tube Blockage Detection & Alert System

Pitot tube blockage remains a significant safety issue in aviation, as it can result in inaccurate airspeed readings and compromised flight performance. This paper presents a Smart Pitot Tube Blockage Detection and Alert System designed to identify and address such failures in real time. The system utilizes an ESP32 microcontroller integrated with a flow sensor to continuously monitor airflow within the pitot tube. A predefined threshold is used to detect abnormal airflow conditions, indicating potential blockages caused by ice, dust, insects, or moisture. Upon detection, a relay-controlled air pump is automatically activated to clear the obstruction, ensuring continued system reliability. An LCD display provides real-time updates on airflow values, system status, and warning alerts, while a push button enables manual operation for maintenance purposes. The proposed system improves aviation safety by enabling early detection, automated corrective action, and clear monitoring, making it suitable for applications in UAVs, ground testing systems, and aviation training environments.
