Abstract

Thermocouple inhomogeneity equipment was developed to measure the seebeck coefficient characteristic in each wire position based on the effect of temperature exposure along the thermocouple wire. Temperature and distance sensors are used to measure the temperature output of the heating system and the movement of the thermocouple position. We developed a real time measurement system to monitor the measurement of the thermocouple sensor based on a microcontroller. The program was compile and upload to ESP 32 then monitoring data with an open source internet of things called Thingspeak is used as a platform to retrieve and display the collected data. Real-time monitoring of distance from ultrasonik and temperature of heat source (heat gun) can be accessed through web applications and smartphones. The data is analyzed real time and base on conditions. This study has been considered successfully implemented that performs on IoT platforms and adaptively ready to monitor thermocouple inhomogeneity equipment.
