This paper proposes the design of sensor based Fault detection & Remote monitoring system for temperature measurement using Atmel AVR controller and LabVIEW. Temperature is an important industrial parameter that needs to be monitored continuously. An entire system may fail; if the sensor fails. The failure of any system may cause losses such as economical, equipment damage and even risks the life of an individual. The purpose of the fault detection system is to ensure that simple faults can be detected at an early stage and necessary actions could be taken so that they do not develop into serious failure or cause any harm and increase plant availability. The fundamental design of fault detection is presented with help of temperature sensors, Atmel AVR development board (Arduino UNO) and Virtual Instrumentation platform (LabVIEW). To demonstrate the concept of sensor fault detection, the system comprises of a closed box with a variable intensity light source and temperature sensors. The temperature data is acquired by embedded module and is transmitted to LabVIEW application serially. Any failure in sensor will be annunciated locally and shall be notified remotely in the web browser panel. The host program on the LabVIEW platform is responsible to publish the data on internet via data socket. The data published is in monitor mode which allows displaying an animated snapshot of the data acquisition panel that updates continuously, enabling the user to monitor it from remote location.

Keywords: Fault detection, Remote monitoring, LabVIEW, AVR Development Board (Arduino UNO).
