Automated greenhouses, powered by IoT technologies, are transforming the agricultural landscape by providing climate precision and smart irrigation to agriculture practices. Based on recent studies, IoT-driven greenhouses can gain yields of up to 30% while reducing water consumption by 20–50% with automated irrigation. Its technology allows it to integrate sensors, actuators, and cloud-based analytics in monitoring and regulating environmental parameters like temperature, humidity, and soil moisture in real-time. Automation of critical processes, such as fertigation, ventilation, and pest control, saves labor cost by an estimated 40% and increases operational efficiency. IoT dashboards enable remote monitoring of greenhouse conditions, providing actionable insights and predictive analytics to enhance the decision-making ability of farmers. Despite the drawbacks of high initial costs and connectivity issues, innovations in AI, renewable energy, and robotics have been driving IoT adoption in greenhouse farming. This paper discusses the potential of IoT to transform agriculture to be sustainable, high-yielding, and resource efficient
