Nine Channel Data Logger to Measure Temperature Distribution on Dry Stelizer based on Andoid system

A temperature measurement in sterilization is needed to find out whether the setting has been reached, because if tool operated continuously it will have an impact on performance of tool. Data logger a used record time and by recording. The purpose this research develop technological advances with remote or automated systems that can monitor changes rise fall. This study uses 9 types K-type thermocouple sensors as gauges which are placed at specified points. connected MAX6675 module for conversion initially detects into digital form data. processing Arduino Mega 2560 system programming software processor.
