Design and Development of Microcontroller based Temperature Scanner

A centralized operation and control facility (COCF) is an integral part of an industrial or scientific venture. COCF performs all the execution of the major plant operations as per the given instructions which are predefined or real-time. The real time section depend inputs from the sensors and actuators installed in the plant for the performance monitoring. These sensors and actuators communicate with the COCF with some standard protocols. The paper presents the design and development of a microcontroller based temperature measurement system universally recommended for any COCF which has a scope of temperature scanning as a prime parameter for the operation using RS232 communication protocol. The system is in a multi-channel configuration considering sensor array. The system is majorly coupled with the temperature sensors like RTD (resistance Temperature Sensor) and thermocouple in the initial design but can be customized for any other temperature sensors pressure sensors and flow sensors.
