PROJECT TITLE :

Embedded system for sensor communication and security

ABSTRACT :

Inter-integrated circuit mode (I2C) software is used to speak between sensors and on embedded control system utilising PIC182585 MPLAB hardware. These sensors were designed as part of a system on-board that has sensors, a Q2 microcontroller and interface circuitry. The hardware includes a PIC18 processor, a field programmable gate array (FPGA) chip and peripherals. The FPGA chip is used to interface the processor with the peripherals operating at the same clock speed. This hardware design options high-level integration, reliability, high precision and high-speed communications. The system was demonstrated using temperature and COa pair of sensors. The system was implemented and successfully tested. The response of the multi-sensor system was agreeable with the design parameters. The system is expandable to incorporate alternative sensors like lightweight and pressure sensors. Monitoring threshold values should raise the safety features of the integrated communication system. The employment of a signature detection algorithm to determine threatening state of affairs and/or intrusion within the sittings are discussed as a possible application for home land security. The integrated system features low-power consumption (utilising the sleeping mode of the processors), high-speed communications, security and flexibility to growth.
