Design and Build Multi Channel Data Logger Connected IoT (Internet Of Things) as a Temperature Meter with a Thermocouple Sensor

    Instrumentation measuring a bthe target is gettingmuch developed along with the rapid developmenttechnology at this time. System measuring instrumentationcommonly used to monitorthe size ring. Wrongone quantitywhich canmonitored is suhu. Monitoringa quantity need data logger for record resultsmeasurement of a object. Data this logger willtake notes accordinglytime to be determined later will save the result datameasurements made.This data loggerdesigned to connectThe IoT where can accessed remotely far usecomputer or smartphones .Device the microcontrollerused is Arduion the MEGA 2560 fromn IoT deviceswhichused is Ethernet Shield W5100. Scensor who willmeasure temperature is a Thermocouple sensor MAX6675 Type-K. The test method carried out in this research arecalibration test sensor, first-order-system to knowtime constant yThe diperlohen from step responwith , and speeddisplacement heat. Results from pengtest obtained rate by ratethe difference betweenbetween sensorswith thermometer Mercuryisless than 1 ℃. Time constant momenttemperature go up andtemperature downtend same bhe said. Hope forward from resultsstudy this is could facilitate user intemperature monitoring which ayes ona locationor temperatureonan object with a measurement difference level of less than 1 .
