Abstract:
The main objective of this project is to develop an embedded system which detects the ambulance entry near the traffic junctions using ZIGBEE. This project is implemented on 8051 based AT89S52 developed board interfaced with traffic indication LED’s, ZIGBEE wireless transceivers.
The main objective of this project is to develop an embedded system which detects the ambulance entry near the traffic junctions using ZIGBEE. The system comprises of two boards one act as the transmitter board and other as the receiver board.
The transmitter board is arranged in the ambulance through ZIGBEE. The receiver board is interfaced with ZIGBEE and a buzzer along with the traffic lights at the junction. Whenever transmitter comes near the receiver it automatically gives buzzer and a direct pass through signal for the ambulance.
The system uses a compact circuitry built around Flash version of AT89S52 microcontroller with a non-volatile memory capable of retaining the password data for over ten years. Programs are developed in embedded C. ISP is used to dump the code into the microcontroller.
This project uses regulated 5V, 750mA power supply. 7805 three terminal voltage regulator is used for voltage regulation. Bridge type full wave rectifier is used to rectify the ac output of secondary of 230/18V step down transformer
