RANCANG BANGUN SISTEM KONTROL TEMPERATUR KENDARAAN LISTRIK BERBASIS SENSOR DS18B20 DAN ARDUINO UNO R3

Abstract

ABSTRAK

Sistem kontrol temperatur pada kendaraan listrik berperan penting dalam mencegah overheating dan menjaga kinerja komponen utama, seperti baterai dan controller. Penelitian ini merancang dan mengimplementasikan sistem kontrol temperatur berbasis sensor suhu digital DS18B20 dan mikrokontroler Arduino Uno R3. Sensor DS18B20 digunakan karena akurasi tinggi (±0,1°C) dan kemampuan komunikasi satu kabel tanpa memerlukan konverter ADC, sehingga efisien untuk pemantauan suhu secara real-time. Data suhu dikirim ke Arduino Uno, yang secara otomatis mengaktifkan kipas pendingin ketika suhu melebihi ambang batas yang ditentukan dan saat suhu melebihi maksimal batas yang ditentukan maka buzzer akan berbunyi untuk menandakan pengguna agar tidak mengoprasikan sepeda motor listrik terlebih dahulu. Pengujian menunjukkan sistem mampu merespons perubahan suhu dengan cepat dan mengendalikan pendinginan secara efektif. Implementasi sistem ini diharapkan dapat meningkatkan keselamatan, efisiensi, dan umur pakai komponen kendaraan listrik.

ABSTRACT

The temperature control system in electric vehicles plays a crucial role in preventing overheating and maintaining the performance of key components, such as the battery and controller. This study proposes and implements a temperature control system based on the DS18B20 digital temperature sensor and the Arduino Uno R3 microcontroller. The DS18B20 sensor is selected due to its high accuracy (±0.1°C) and one-wire communication capability, which eliminates the need for an external analog-to-digital converter (ADC), making it efficient for real-time temperature monitoring. Temperature data acquired by the sensor are transmitted to the Arduino Uno, which automatically activates a cooling fan when the temperature exceeds a predefined threshold. Furthermore, when the temperature surpasses the maximum allowable limit, a buzzer is triggered to alert the user to temporarily avoid operating the electric motorcycle. Experimental results demonstrate that the system responds rapidly to temperature variations and effectively regulates the cooling process. The implementation of this system is expected to enhance safety, improve operational efficiency, and extend the service life of electric vehicle components..
