IoT-based garden automation “Green Connect” is a system that automates and tracks numerous gardening-related operations using internet-connected sensors and devices. Benefits of this technology include enhanced plant growth, improved watering schedules, and remote monitoring and management of plants. The system is made up of numerous parts, including irrigation sys-tems, temperature sensors, humidity sensors, and soil moisture sensors, all of which are linked to a central hub. In order to automate the watering, lighting, and other environmental conditions of the garden, the microcontroller gathers and analyses the data from the sensors. The development of an IoT-based garden automation system is covered in this article, along with the design of the system architecture, component selection, optical sensor and device integration. The experiment's findings demonstrate that the system was able to improve the garden's growth conditions, leading to better plant health and yield. According to the study, IoT-based garden automation has the ability to completely change how we think about gardening by making it simpler and more effective to grow plants in a range of settings. By remotely managing the water pump and keeping track of the soil moisture in the garden, this study integrates the IoT into the irrigation system for gardens.
