Abstract: The drone market has seen a surge in the past few years and the number of consumer drones has been on the increase. With even beginners starting to fly drones, there is a serious safety issue of whether the drone will crash because of technical and unforeseen problems. It may lead to injury of people going about their day and may even cause damage to material things on the ground and naturally damage the drone itself. So, there is a need for a new system which would substantially prevent these kinds of problems. The Emergency Drone System (EDR) will be a solution and will be a versatile fit in all drones. The EDR system uses the MPU-6050 gyroscope and accelerometer sensor along with MPL3115A2 Pressure based Altitude sensor to get input on the real-time movement of the drone and analyses using the algorithm coded into the Raspberry Pi using Python programming language. Apart from this, it also inputs data from the flight controller and analyses it. The parameters such as the altitude, rate of rotation and rate of fall are calculated and based on the algorithm if any kind of anomaly is detected it is programmed to deploy the parachute which will automatically prevent the crashing of the drone. So by which the crashing of drone and damage to property is prevented and safety of people below the drone is ensured.
