Abstract

The unwise use of electrical energy in households can lead to energy wastage and pose risks such as short circuits, which may result in fires. This research developed a Node-Red-based protection system using an ESP8266 microcontroller and a PZEM 004-T sensor to detect voltage, current, and power in real-time. The system automatically disconnects the current when overload conditions are detected, especially on extension cables. Testing was conducted on household devices such as laptop chargers, fans, and soldering irons. Results demonstrate that the system can accurately monitor current and power, maintain electrical stability, and cut off electricity when the load exceeds the safe threshold, thus reducing fire risk. This implementation is expected to enhance household electrical safety and serve as a reference for further development in IoT-based protection systems.

Abstract

The rapid advancement of technology has led to an increasing demand for electrical energy. One of the efforts to meet this demand is the development of micro-capacity power generation systems utilizing heat energy. Heat energy can be harnessed using thermoelectric elements. This study aims to design and develop a portable power generation system that utilizes solar heat as an energy source. The prototype uses six TEC 1-12706 thermoelectric modules to generate electricity designed specifically to recharge devices such as phones, power banks, and flashlights. Solar heat is concentrated on the thermoelectric modules using Fresnel lenses, while heatsinks are employed for cooling. The thermoelectric modules are connected in series to produce sufficient voltage, which is then boosted by a boost converter. The generated electrical energy is stored in a battery to ensure voltage stability despite temperature fluctuations. This device can also operate at night due to the energy stored in the battery. Test results show that the average output voltage without load ranges from 9.49V to 9.56V, with an average temperature of 45.2°C at the thermoelectric modules. In load tests, the device successfully charged a Pixel 5 phone (5000 mAh battery) from 4% to 70% in 95 minutes. These results demonstrate the potential of this system as a reliable and environmentally friendly portable energy solution.

Abstract

Penelitian ini bertujuan untuk merancang dan menguji prototipe smart solar tracker dual axis yang terinspirasi dari gerakan bunga matahari dalam mengikuti arah matahari, dengan tujuan memaksimalkan penyerapan energi pada panel surya. Sistem smart solar tracker ini didesain agar panel dapat bergerak secara otomatis pada dua sumbu (horizontal dan vertical) sehingga orientasi panel selalu optimal terhadap posisi matahari sepanjang hari. Pengujian dilakukan dengan menggunakan mini panel surya pada rentang waktu pukul 10:00 hingga 15:00 WIB di kota Surabaya selama tujuh hari, dengan pengamatan perubahan voltase dan output charger pada kondisi cuaca yang beragam. Hasil pengujian menunjukkan bahwa sistem smart solar tracker dual axis mampu meningkatkan efisiensi penyerapan energi, ditunjukkan dengan rata-rata voltase sebesar 11,05 V dan output charger sebesar 5,10 V pada kondisi cuaca cerah. Meskipun terjadi penurunan kinerja pada kondisi cuaca berawan, sistem ini secara keseluruhan terbukti lebih efektif dibandingkan panel statis dalam mempertahankan daya keluaran yang konsisten. Rancangan yang terinspirasi dari mekanisme pergerakan bunga matahari berhasil diterapkan pada sistem tracking, sehingga panel dapat terus menyesuaikan posisinya sesuai perubahan posisi matahari. Sebagai tindak lanjut, disarankan pengembangan algoritma pelacakan yang lebih adaptif terhadap perubahan intensitas cahaya pada cuaca berawan, penggunaan sensor cahaya berpresisi tinggi, dan implementasi prototipe pada panel dengan kapasitas lebih besar untuk hasil yang lebih akurat. Melalui hasil penelitian ini, prototipe smart solar tracker dual axis berbasis gerakan bunga matahari diharapkan dapat menjadi solusi dalam optimalisasi penggunaan energi surya secara lebih efisien dan berkelanjutan.

Abstract

The need for a smart grid has been spurred by the growth of distributed generation, the aging of the current grid infrastructure, and the desire to alter networks. The development and enhancement of smart grid technology is significantly facilitated by the Internet of Things (IoT) technology. Batteries play a crucial role in the energy storage of electrical systems, including smart microgrids and electric vehicles. To enhance performance and prolong battery life, a Battery Monitoring System (BMS) is required to manage the energy storage process dynamics within the battery. Battery life prediction contributes to the consistent and efficient operation of battery-powered devices. This research presents battery charging monitoring using Nodered. Apart from that, the battery charging feature uses a cut-off concept. The cut off on the battery is to prevent the battery from over-discharging which can damage the battery and shorten its lifespan. This research carried out validation using 3 case studies on battery charging. Validation of measurements uses a comparison between the INA 219 sensor and a multimeter. From experiments, current testing from 3 case studies, it was found that the average difference in current sensor error was 0.19%.
