Smart vacuum flask with beverage identifier and temperature indicator / Mario Apok & Wilzy James

Nowadays, vacuum flask is an important device that can fulfill the demand of convenient life and energy saving method. The users normally have difficulty to determine the temperature of drinks or food and likely to forgot what the keep in their thermos. Therefore, we came out with idea to add electronic features to the thermos with are temperature indicator and beverage identifier. For the temperature indicator, we use LM35 as our temperature sensor and Arduino Uno acts as microcontroller while for beverage identifier we use Light Dependent Resistor, LDR as sensor with the concept of tomography. Based on the result, we able to tackle the problems where thermos able to indicate temperature and able to identify the type of beverage in the thermos. In conclusion, we successfully solve the user difficulties using thermos with the additional electronic features.
