People with visual disability unable to recognize the nominal of banknotes in conducting economic life, hence, rely on their touch and hear senses to recognize the banknotes. In this work, we investigated the LDR sensor to detect the nominal value of banknotes with voice output. It was found that the error rate 100% for IDR 2000, IDR 10000, IDR 100000, and IDR 50000, 75% error rate was for IDR 5000 and IDR 2000, and 50% error rate for IDR 1000.
