Sistem Pengontrol Suhu, Kelembapan dan Intensitas Cahaya pada Rumah Kaca Berbasis Internet of Things (Iot) Menggunakan Blynk

Abstract

This study introduces an IoT-based system designed to regulate temperature, humidity, and light intensity in a greenhouse using the Blynk platform. The system ensures real-time monitoring and control of environmental conditions, specifically maintaining temperatures between 25-35°C and humidity levels of 70-85%. The core components include the DHT22 sensor, BH1750 sensor, and NodeMCU ESP32, alongside supporting devices such as fans, blowers, and lights, which operate autonomously based on sensor readings. The development process encompassed hardware and software design, sensor testing, and calibration. System evaluations conducted under different environmental conditions confirmed its effectiveness in stabilizing temperature and humidity while optimizing energy consumption by activating devices only when necessary. The integration of IoT technology enables remote monitoring via the Blynk application, simplifying greenhouse management. This research contributes to advancing environmental automation technology, particularly in IoT-driven agricultural applications, and provides a basis for further innovations in industrial and societal applications.
