Rancang Bangun Sistem Penyiraman Tanaman Berbasis IoT Menggunakan Soil Moisture Sensor Dan Dht-22

Abstract

This study aims to design and develop an automatic plant watering system based on the Internet of Things (IoT) using the ESP32 microcontroller, soil moisture sensor, and DHT-22 sensor. The system automatically activates the water pump when the soil moisture level drops below a predefined threshold (<60%). The soil moisture sensor monitors the condition of the planting medium, while the DHT-22 sensor measures ambient temperature and humidity around the plant. The system is integrated with the Telegram platform via an internet connection, allowing users to monitor plant conditions in real-time and manually control the watering process remotely. Automatic notifications are sent to Telegram, providing information about soil moisture levels, temperature and humidity, and pump status (active/inactive). Test results show that the system operates effectively and offers users convenience and efficiency in plant maintenance without the need to be physically present.
