Vegetable oil is the type of oil that is most widely used by humans for consumption purposes, some of these oils are difficult to physically distinguish. The difference from the types of vegetable oils needs to be known so that they can be consumed according to needs. The proper use of vegetable oils for consumption also affects health. The difference from the types of vegetable oils can be seen based on physicochemical parameters, which use thermal conductivity by measuring the value of current (I) and voltage (V). Measurements are based on the I(V) curve generated by the Positive Temperature Coefficient (PTC) sensor, which is connected to the sensor level LX-01 module. The measurement results are displayed through sensor-level software, where the output is in the form of current and voltage values. Canola oil has a voltage of 6.9235 V with a maximum current of 0.0764 A. Corn Oil has a voltage of 7.9256 V with a maximum current of 0.0744 A. Soybean Oil has a maximum current value of 0.0752 A with a voltage of 6.9248 V.
