    This thesis presents Smart Garden, a mesh-networked IoT system that addresses the challenge of determining the right time to water indoor plants. Unlike existing solutions that operate as standalone units, Smart Garden employs sensors in a mesh network, enabling monitoring in areas with poor coverage. The system continuously tracks soil moisture via capacitive sensors, transmits data through a mesh network, and notifies users through a web interface when plants need watering. Testing demonstrated 96% reliability over three months and successful communication through concrete barriers. Evaluation confirmed that the system effectively transforms the question of ”When do I water my plants?” into actionable notifications based on actual soil moisture data.
