Abstract

ABSTRAKPenelitian ini bertujuan mengembangkan sistem pemantauan temperatur dan kelembaban udara di Smart Greenhouse Lembang Agri. Sistem ini terdiri dari beberapa perangkat yang saling terhubung untuk mengukur temperatur dan kelembapan secara nirkabel. Data pengukuran dikumpulkan lalu dikirim ke internet. Setiap perangkat memiliki sumber daya mandiri yang berasal dari baterai dan dapat dihubungkan ke sistem panel surya. Penelitian ini menggunakan mikrokontroller WEMOS D1 Mini dan memanfaatkan protokol ESP-NOW untuk transmisi data nirkabel. Sensor yang digunakan adalah DHT21 dengan performa lebih unggul dibandingkan sensor DHT11 atau DHT22. Tampilan website menggunakan PHP untuk menerima, memvalidasi, dan menyimpan data di Firebase Real-time Database. Website dilengkapi fitur agar pengguna dapat mengakses data real-time dan historis untuk setiap perangkat.Kata kunci: smart farming, ESP-NOW, ESP8266, gateway, panel surya, portabel ABSTRACTThis study aimed to develop a monitoring system for air temperature and humidity in the Lembang Agri Smart Greenhouse. This system consists of multiple interconnected devices that can wirelessly measure temperature and humidity. Measurement data is collected and then sent to the internet. Each device has an independent power source derived from the battery and can connect to a photovoltaic system. This study uses the WEMOS D1 Mini microcontroller and enabling wireless data transmission through the ESP-NOW protocol. The sensor employed in this study is the DHT21, known for its superior performance compared to the DHT11 or DHT22 sensors. The website dashboard utilises PHP to receive, validate, and store the data in the Firebase Real-time Database. The Website features allow users to access real-time and historical data for each device.Keywords: smart farming, ESP-NOW, ESP8266, gateway, Photo Voltaic, portable

Abstract

Unpredictable climate change poses significant challenges for farmers at Gapoktan Lembang Agri in maintaining sustainable production. To support quick and precise decision-making, a mobile-based monitoring system has been developed, enabling real-time monitoring of greenhouse temperature and humidity through an Android application. This system utilizes IoT sensors to measure environmental parameters, with the collected data transmitted to a server via the internet and displayed directly in the application. The application is designed using Jetpack Compose to ensure a responsive and user-friendly interface, even for users with limited technical knowledge. Firebase is employed as a real-time data management platform to guarantee data accuracy and processing speed. Key features include live monitoring, access to historical data, and data export capabilities for further analysis. The system has been successfully implemented and tested in the greenhouse of Gapoktan Lembang Agri, demonstrating its ability to provide real-time monitoring and accurate data. Feedback from users indicates ease of use and the application's effectiveness in helping farmers respond proactively to environmental changes.
