TEMPREATURE SENSING BY USING GSM MODULE WITH THE HELP OF FPGA

Abstract

FPGAs (Filed programmable Gate Array) have become a competitive alternative for high performance DSP applications, previously dominated by general purpose DSP and ASIC (Application Specific Integrated Circuit) devices. In this design based on using FPGA for the hardware implementation of the controller circuit and GSM (Global System for Mobile) for remote monitoring. The controller circuit has been described using VHDL (VHSIC Hardware Description Language). The design has been simulated using ModelSim from Model Technology and implemented using Xilinx ISE software tools. FPGA Spartan2 starter kit from Digilent has been used for the hardware implementation of the controller circuit. The system offers low cost and user friendly way of 24hours real-time remote monitoring for temperature using SMS (Short Messaging Service) messages.
