Design of Solar Panel Light Monitoring and Controllers Using a Web-Based Arduino

In the Modern Era, a source of electrical energy is very necessary, given the large number of electronic equipment that really requires a source of electrical energy. Solarcell is a device or component that can convert light energy into electrical energy. However, the energy used in this solar panel needs to be considered the efficiency of its use. Therefore it is necessary to monitor currents and voltages and loads in real time to determine the energy needs of solar panels for lamps. Monitoring of voltage, load and current on this solar panel is based on a microcontroller. The voltage generated by the solar panel and the battery voltage is measured using a sensor. It takes a Web and a modem device to send solar panel measurement data from a distance, with remote monitoring makes it easier to find out what the voltage and load is without having to be in place of the solar panel. Web as a control for lights, blackouts, dim and bright lights, on the web can monitor voltage and current values. The results of the microcontroller ADC are able to send data to the web. The data stored in the ms.excel file contains the voltage from the solar cell, the current at the load and the time when storing and charging the battery. The lights can only last 5 hours when all loads are active (ON), while charging (charging) for 13 hours when the battery is empty.

Optical and Electrical Properties of Transparent Carbon Nanofilm Sandwiched between Transparent Alumina Determined Using a Touch Technique

This study investigated the optical and electric properties of carbon nanofilms for capacitive application. The carbon nanofilms were sandwiched between alumina layers, and the specimens were covered with SiO2 nanofilm. Aluminum patterns were inscribed and used to determine the contact location. The optical and electrical properties of the transparent nanofilms were measured as the specimen was used as a touch panel. Light transmittance, film thickness, spacing, voltage, resistance, and electrical current were measured. Finally, an LCR meter was used to measure the inductive capacitance points. Glass was used as the substrate in this study. Carbon graphite was sputtered onto a metastable aluminum nanofilm, which was then cured. This carbon transits from an excellent conductivity (sp2 -bonded) to an insulating (sp3 -bonded). Metal can be transparent at the nanoscale, and its metastability can be sustained for a few hours. Graphite was sputtered onto aluminum nanofilm, and the carbon layer contained weak dipoles, resulting in weak capacitance. Consequently, sp3 bonding was dominant after curing. The transparency and capacitance of the samples was related to the thickness of and pattern in the aluminum layer.
