The objective of this study is to design a temperature measurement system based on a non-contact method using a sensor camera from a webcam. The material being measured is nickel wire given an electrical current of 4.5 A–6.5 A with an interval of 0.5 A. The temperature measurement is based upon the measurement of the average pixel value distribution of infrared (IR) electromagnetic waves emitted by the measured material, i.e.: the nickel wire. The IR waves are passed through a diffraction grating and then captured by the sensor camera consisting of red, green, and blue layers. Calculation of the temperature is conducted by way of Planckian distribution as a model for the average pixel value distribution in the IR regions producing Wien’s displacement law. Results show that the IR wavelength at maximum average pixel value shifts to a shorter wavelength as the nickel wire is heated in accordance with Wien’s displacement law. Moreover, the Wien’s constant is recovered for the temperature calculation of the red and green layers, which shows the best model for the non-contact measurement system. However, the temperature measurement still contains a systematic error that shifts the calculated temperature in contrast to the true temperature. This systematic error may be reduced by adjusting the measurement system set-up.

This paper reports the performance of the flexible nanogenerator as a green energy harvester depends on connection variation. The ZnO nanogenerator was successfully fabricated on Al/PET. The ZnO Nanorods were synthesized using a hydrothermal method at 95°C. The ZnO Nanorods were characterized using x-ray diffraction (XRD), scanning electron microscopy (SEM), fourier transforms infrared spectroscopy (FTIR), and UV-Vis spectrophotometer. The performance of the nanogenerator was performed using Osiloscop and electrometer in series and parallel connection. Based on the XRD pattern, ZnO sample has a hexagonal (wurtzite) crystal structure in which the lattice parameters of a = b, and c = 3.258 Å, and 5.218 Å, respectively. The morphology of ZnO is a hexagonal form with diameters of 81,06 nm to 467.69 nm and rod length around 595 nm to 1331 nm. Based on the FTIR spectra, there are Zn-O bonds at 435-445 cm-1, 535 cm–1 and, 541 cm-1. Moreover, ZnO nanorods have an energy gap band of 3.2 eV. The performance of the ZnO nanogenerator in series form has the highest voltage with a value of 10.36 volts AC, and the voltage value in dual-source is more than ten times larger compared to a single source.
