| This study focused on the design of a surveillance quadcopter that can be used in search operations on isolated places that cannot be easily reached by humans in the aftermath of calamities such as typhoons, earthquakes, tidal surges, and others. It also aimed to integrate data logging of weather elements such as temperature, humidity and air pressure to be used for research and further studies about weather. The design of the project consists of an Arduino Leonardo Board which processes the gathered measurement of the GPS module (latitude and longitude), DHT11 sensor (humidity and temperature) and Adafruit 10 DOF Sensor (height, barometric pressure, roll, pitch and yaw). It is then connected to a Raspberry Pi B+ for the data to be sent wirelessly in the ground station laptop using a 2.4GHz TP-Link WiFi dongle. SJ4000 12MP action camera is used to gather video to be saved and streamed in the laptop. For the flight functions, the researchers used HK Pilot Mega 2.7 Flight Controller integrated with a power distribution board and electronic speed controllers to control to the movements of the quadcopter by varying the speed of the motors. Several tests were conducted to determine how this developed system operates and functions based on the objectives of the study. The accuracy of measurements, flight stability, quality of video, flight time and maximum distance were tested and evaluated by the personnel of City Disaster Risk Reduction Management Office. The system produced a reliability of 92.5% for flight functions, 92% for data telemetry and logging and 73.33% for video gathering, for a total system reliability of 85.94%. |
