Multimeter is the most widely used tool by a technician in measuring electric current, especially AC current and DC current. However, when making a measurement, technicians often divide their focus into two directions: the measurement results displayed on the multimeter and the electrical equipment being measured. This makes the technician unfocused so that it can cause work accidents. The purpose of this research is to design and make voltmeter glasses that can help technicians in measuring electrical voltage. The results of testing the tool are carried out by comparing the results of voltage measurements using a multimeter with the results displayed on smart glasses and measuring instruments made. This tool uses a wireless communication system with the Bluetooth working principle. On the voltmeter side, the Arduino nano is connected to the ZMPT101B voltage sensor and the ACS712 sensor which can measure AC and DC voltages and also uses Bluetooth hc-05 as a link to the glasses on the glasses using the ESP32 as a microcontroller connected to the oled display as displaying the measurement results from the voltmeter reflected from the mirror to the glasses. Also in the glasses there is a battery as power to run the glasses as well as a charger controller as a charger on the battery. The final results of the study show that the measurement of voltmeter glasses with a multimeter is not too different and only a slight difference and the results are quite accurate.
