Smart gardening is more than just a laboratory experiment in today's world. The system enables water conservation and energy efficiency. Furthermore, it also improves plant health and increases production rate. Traditional methods involved a constant need to physically attend to the garden to water the plants. This task effectively gets easier with preinstalled water channels and mobile interfaces. The Internet of Things (IoT) can be a game-changer for the entire gardening experience. The challenges to implementing the system include understanding the plant's needs, and knowing how to operate the app interface. IoT can play a huge role in monitoring our garden remotely. This research proposes the idea of going a step ahead in terms of using automation for gardening experience. With the signature autopilot mode, the user app can control the automation, and the user does not need to turn on the water pump even from the app interface. Under certain set conditions, sensors will auto-detect garden status and start or stop machines based on pre-defined conditions. Through proper mathematical analysis and algorithmic approach, this work presents a great option for elderly people who find it difficult to water plants physically.
