Abstract: The drones and possibilities of their using.the discussed construction of drone, important elements are propeller,engine,power distribution,flight controlsystem,electronic control and communication system.Drone is related with lift,roll,yaw. The drone control system was triggered.An Android mobile device with GPS was used for live location of the drone and real-time audio visual view from the drones of which carbonmonoxide(CO),alcohol (OH),liquefied petroleum gas.(LPG),smoke.LPG and CH4 leakage from site is associated with natural gas protection, detecting leaks sites compared to traditional manual method.Drone strategy and relative study on aerial survey height of system are those crucial factors to optimize the leak rate estimation.

Keywords: Drone, Unmanned aerial vehicle, Aerial surveillance, Gas leakage detection, Aurdino board, leak rate quantification.
