An Effective FPGA Based Real Time System for Measuring Temperature and Light Intensity Using UART Protocol

This research study has developed an efficient FPGA based temperature and Light intensity measurement system to reads the temperature and light intensity values through XADC using UART protocol and displays it on LCD updated to every second time period. The LM35 and LDR sensors are used as a temperature and light intensity sensors and are interfaced with the FPGA (ARTIX-7) manufactured by Xilinx. The signal processing system, which transforms the output into quantized voltage levels before sending it as an input to an ADC, is coupled to the output generated by the sensors. The necessary code is written in the hardware description language VHDL. Xilinx VIVADO suite is used for software development which is one of the EDA (Electronic Design Automation) tool offered by the Xilinx Company. The purpose of this project is to lower the power usage and continuously update the temperature and light intensity using a 28nm FPGA device.
