The main aim of this project is to design a wireless sensor network for vehicle to calculate the vehicle emissions using sensors.The purpose of the project is to calculate the quantity of CO2 released from the vehicle and to transmit this data to the near by R.T.A using zigbee and GPS technologies.
The project consists of two parts one is transmitter section and other is receiver section. From the transmitter section the quantity of gas released will be measured and given to the ADC as input. ADC will convert this analogical data into digital format and forwards to the controller. Microcontroller compares this data with predefined data; if it exceeds the threshold then zigbee transceiver is activated. From the GPS current location of vehicle is given to the controller. Zigbee transceivers will transmits this data to the receiver part which is located in the R.T.A office. If incase the smoke intensity is more than the limit, the buzzer which is attached to the vehicle will buzz for three times, that intimates to the driver that smoke intensity is high, please reduce it. Still it is not reduced the vehicle will stop automatically.
GPS (Global Positioning System) technology is used to find the location of any object or vehicle to monitor continuously using satellite signals. Three satellite signals are necessary to locate the receiver in 3D space and fourth satellite is used for time accuracy. GPS will give the information of parameters like longitude, latitude and attitude. With the help of these parameters one can easily locate the position of any object. In this GPS technology, the communication takes place between GPS transceiver and GPS satellite.
Zigbee is new wireless technology guided by IEEE 802.15.4 Personal Area Network standard. It is primarily designed for the wide ranging controlling applications and to replace the existing non-standard technologies. It currently operates in 868MHz band at a data rate of 20Kbps in Europe, 914MHz band at 40kbps in USA, and the 2.4GHz ISM bands Worldwide at a maximum data-rate of 250kbps.
