"A rooftop greenhouse faces several challenges, including human error and high\r\ntemperatures. Due to its relatively small size, a hydroponic system, specifically the\r\nebb and flow method, was chosen to maintain optimal soil moisture levels. Based\r\non these challenges, this research aims to design and develop an automated system\r\ncapable of regulating soil moisture for plant seedlings within the greenhouse. The\r\nsystem utilizes a Wemos D1 R1 microcontroller, a YL-69 soil moisture sensor, an\r\nHC-SR04 water level sensor, and a DHT22 temperature and humidity sensor. The\r\nsystem is connected to a database via Wi-Fi and can be accessed through an app or\r\nweb browser. The research findings indicate that the system effectively controls soil\r\nmoisture by reading data from the YL-69 sensor. The system automatically waters\r\nthe plants when soil moisture drops below 70% and drains excess water when it\r\nreaches 75%. To prevent overfilling, the HC-SR04 sensor monitors water level and\r\nactivates solenoids and pumps to adjust water levels accordingly, turning off when\r\nthe water reaches 15cm during filling and 4cm during draining."^^ .
