Abstract

Lately, there are frequent fires caused by human factors. Because we cannot predict the process of fire in advance. And the delay in knowing the occurrence of a fire is very fatal to the safety of human life and property. With advances in technology, we can overcome fires by making early fire detection devices. With the presence of temperature and smoke detectors, we can detect fires as early as possible and be delivered quickly via alarms and SMS gateways. The main component of this fire detector is the Arduino Uno. This Arduino uno acts as the brain of the fire detection device. This tool works based on the detection of the temperature condition by the DHT11 temperature sensor, which is when the temperature is above normal, an alert notification will be sent via the SMS gateway and so will the MQ2 smoke and the buzzer will sound as a warning alarm.

Abstract

The community's need for electricity is getting higher, so alternative energy sources such as solar heat are needed to replace energy sources from fossil fuels in meeting electricity needs. In this paper we design a two-axis solar tracker with an LDR sensor. A sun tracking system is a unit that is combined into one to control the position of the tracking device with the aim of making the surface of the solar panel module always facing the direction of sunlight. This research discusses the Prototype of the Sun Tracking System in Arduino Based Solar Power Generation Systems to get maximum solar energy. This system will make solar panels move automatically so that sunlight absorption can be maximized. The main control uses Arduino nano which gets input values ​​from the LDR sensor then is processed to the output system. With the control system method can automatically be seen the difference in the results of a fixed solar panel with a solar panel with a tracker, from the comparison we get a solar panel with a tracker to get more optimal results.

Abstract

Kebutuhan masyarakat akan listrik semakin tinggi, sehingga sumber energi alternatif seperti panas matahari diperlukan untuk menggantikan sumber energi yang berasal dari bahan bakar fosil dalam memenuhi kebutuhan listrik. Dalam tulisan ini kami membuat desain pelacak surya dua sumbu dengan sensor LDR. Penelitian ini membahas Prototipe Sistem Pelacakan Matahari dalam Sistem Pembangkit Listrik Tenaga Surya Berbasis Arduino untuk mendapatkan energi surya maksimum. Sistem ini akan membuat panel surya bergerak mengikuti gerakan matahari, sehingga penyerapan sinar matahari dapat dimaksimalkan. Agar panel surya dapat bergerak mengikuti sinar matahari, maka kita membutuhkan sistem kontrol otomatis. Kontrol utama menggunakan Arduino nano yang mendapat nilai input dari sensor LDR kemudian diproses ke sistem output. Dengan metode sistem kontrol secara otomatis dapat terlihat perbedaan hasil panel surya tetap dengan panel surya dengan tracker, dari perbandingan panel surya dengan tracker lebih optimal dalam menerima sinar matahari dibandingkan dengan panel surya tetap.
