Abstract
The study of the heat created during chemical reaction is important in order to get to the basic understanding of the heat of reaction (reaction enthalpy), bound enthalpy and chemical equilibrium. In this research, a calorimeter was developed by using a digital thermal sensor to measure the thermal change during the chemical reaction and using a NodeMCU ESP8266 board with IoT controller to send the data to Blynk application on smartphone to be displayed, tracked, and recorded. The thermal changing data will be displayed in graph which will specify reaction type; endothermal or exothermal reaction, and show the amount of the heat during the reaction. In addition, this is a real-time thermal changing data collection instrument that can also send the data directly to a personal computer. It will simplify the experiment process and reduce data collection error from observer with percent accuracy of 96.44.
