• Calorimeter based on Arduino Mega microcontroller has been created using the DS18B20 temperature sensor and Load Cell sensor. Arduino Mega Microcontroller also features HX711 module to measure mixed temperature inside calorimeter. The reading results of mass and a mixed temperature inside calorimeter display on the Android smartphone screen with the help of Bluetooth HC-05 wireless communication media. The use of Arduino Mega microcontroller to determine the specific heat of an object indirectly. Calorimeter based on Arduino Mega microcontroller aims to reduce manual measurement error. The temperature measurement calibration for the DS18B20 temperature sensor has a relative error of 4.36% and for the digital thermometer has a relative error of 4.62%. The calibration results of mass measurement for Load Cell sensor have a relative error of 4.10%. The calibration results of mass measurement for Digital Scales have a relative error of 4.14%.
