System Design Temperature Data Logger Based on LabVIEW 8.5

Abstract

Labview based temperature data logger system design has a basic concept as a system of receiving, processing, and compiling temperature data that is controlled by an AVR microsystem that will communicate bidirectionally with LabVIEW using the RS232 serial communication method. The temperature sensor used is LM 35 ,. The LM 35 temperature sensor is connected to the AVR microcontroller via port A to convert analog output to digital and temperature data will be transmitted to the computer using serial communication to be displayed and processed by the microcontroller system (based on the application program that is embedded in the memory). In the main program labVIEW 8.5 application, the data is then processed into data logger information. Result information is not only displayed on a computer monitor screen, it is also stored in an external memory (hard drive).Keywords: LabVIEW 8.5, AVR microsystem, LM 35, Serial Communication
