The document describes the design and development of a vehicle monitoring system using a PIC microcontroller and CAN protocol. The system monitors various vehicle parameters like temperature, CO levels, battery voltage, and light detection through CAN communication between sensor nodes and a display node. It aims to provide real-time monitoring of these factors as an improvement over traditional peer-to-peer electronic control unit connections. Key hardware includes PIC microcontrollers, sensors, an LCD display, and CAN controller and transceiver chips. The system is programmed using embedded C and can potentially be applied to monitor vehicles.

- 1. DESIGN AND DEVELOPMENT OF PIC MICROCONTROLLER BASED VEHICLE MONITORING SYSTEM USING CONTROLLER AREA NETWORK (CAN) PROTOCOL Introduction: Controller Area Network (CAN) is an attractive alternative in the automotive and automation industries due to its ease in use, low cost and provided reduction in wiring complexity. It was developed by Robert Bosch for communication between various digital devices inside an automobile where heavy electrical interferences and mechanical vibrations are present. This project is aimed at the implementation of CAN protocol using PIC for vehicle monitoring system. The main feature of the system includes monitoring of various vehicle parameters such as Temperature, presence of CO level in the exhaust, Battery Voltage and Light due to spark or fire. Existing System: The traditional forms of peer-to-peer connect between electronic control units and electronic devices cannot meet the need of real time control of distributed system in automobile. Meanwhile, the continuing increase of electronic devices results in geometric growth of lead number and wiring becomes hard in limited space in automobile, restricts the expansion of internal control functions. ProposedSystem: In the proposed system we can monitor various vehicle parameters such as Temperature, CO percentage in the exhaust, Battery Voltage and LDR through CAN protocol. The temperature sensor, gas sensor and LDR is connected to the PIC16F877A Microcontroller. The battery voltage is reduced using a potentiometer so that it can be applied to the microcontroller for monitoring. All the four parameters are continuously monitored using the PIC Microcontroller. The display node consists of a PIC Microcontroller with an LCD display. The communication between the two nodes is established using CAN Network that is CAN transceiver and CAN
