dc.description.abstractIn each type of liquids contents physical material that has a conductivity to deliver a current. More or less the conductivity in a liquid defines ability to deliver electrical power. The aim of this research is to measure the conductivity level of liquid with microcontroller and compare which liquid that has a higher ability to deliver the electrical power. Measurement of conductivity from a liquid can be done through censor, Analog to Digital Converter (ADC), microcontroller AT89C51 and Liquid Cristal Display (LCD). Censor will be connected in parallel with a resistor to get a voltage divider. The voltage in censor will be varied depend on the level of measured resistance. The conductivity can be seen when censor is put in a liquid. The voltage fluctuates before it achieves the stability. ADC converts the analog value (from censor) to digital value. Microcontroller gets the data of voltage from ADC, process it and send the result to LCD. In this research, the liquid used are sulphate acid, alcohol, methylated spirit and lead acid battery. So, it can be identified which liquid has a higher ability to deliver the electrical power. The result shows that alcohol has a higher electrical power delivery rather than sulphate acid, methylated spirit and lead acid battery. On the other hand, lead acid battery has lower electrical power delivery than sulphate acid, alcohol and methylated spirit. The maximum percentage of fault from the measurement is 1.3%.en_US
