The Main Aim This Project Is Preventing The Aeronautical Crashes. Hardware Requirements Are RF Transmitter (STT-433MHz)/Receiver (STR-433MHz), Microcontroller , Encoder-318, Decoder-318, LCD (16×2 And 20×2), , Buzzer And Power Supply. Transmitter Contains Encoder, Which Takes Parallel Data From Microcontroller As Input And Gives Serial Output. Whereas Receiver Takes Serial Input And Gives Parallel Output To The Microcontroller. Compare To Microprocessor Microcontroller Has Three Level Programmable Clocks And Low Power Consumption. This Data Is Processed In Receiver And Drives The Motors In Opposite Direction. All The Status Will Be Displayed In LCD. This Unit Is Placed In Flight. Every Aero Plane Contains Both Transmitter And Receiver; This Mechanism Will Depend On Ip Address. Transmitter Sends The Ip Address Of Aero Plane To Receiver Of Other. Receiver Receives Ip Address Of Other Aero Plane. If Any Information Is There Transmitter Sends, Then The Receiver Buzzer Will Glow And Produce Sound. So There Is A Chance To Crashing Aero Planes. Then We Have To Divert The Both Aero Planes To Its Initial Position. So No Chance To Crash.
