Data acquisition system based on 8051 microcontroller for cutting tool temperature measurement

In the present study, Intel 8051 microcontroller based data acquisition system using the temperature sensor LM35 has been developed for measuring the cutting tool temperature. It involves conversion of signal from the sensor which senses the temperature of the tool, into digital output through ADC circuit and fetched by the computer via RS-232 interface with the help of microcontroller. It provides real time data of the temperature of the tool and can be used for tool temperature measurement. It is accurate and cost effective.
