Water scarcity is one of the major challenges in modern agriculture, especially for small-scale farmers. Efficient water management is essential to improve crop productivity while reducing wastage. This study focuses on the design and evaluation of an IoT-based automatic bottle drip irrigation system. The system integrates soil moisture sensors, a microcontroller, and a water pump connected to recycled plastic bottles to provide controlled irrigation. The experiment was conducted in a small experimental field using a selected vegetable crop. Soil moisture levels were monitored continuously, and irrigation was automatically triggered when moisture dropped below the set threshold value. Results showed improved water-use efficiency and reduced manual labour compared to conventional irrigation methods. The system proved to be low-cost, sustainable, and suitable for small land holdings
