Quadcopter is a flying robot that has quite high potential to fall. There are many factors that can cause quadcopter fallen as it meet strong winds, crashing into buildings or trees, running out of power when it flying high, the control mechanism and the electrical system is damaged, or the flight control program has a problem . This research offers a safety system on quadcopter, using an automatic parachute and sms delivery system. This security system starts to enter data from the altitude reading by BMP180 sensor and location data from the GPS. And then it is sent to the microcontroller to be processed. When there is a condition called fall, the microcontroller will send a commands to the GSM module to send sms on the location and servo to open the parachute tube. By implementing this system on quadcopter is expected to decrease the adverse effects that would occur when quadcopter fall.
