Project Idea
Automate plant watering using a soil moisture sensor and microcontroller. This smart irrigation system detects soil dryness and activates a water pump when needed, ensuring optimal hydration without overwatering. Ideal for home gardens, small farms, and educational automation projects.
Project Description
The Smart Plant Irrigation System is designed to monitor soil moisture and water plants automatically based on real-time data. An Arduino Uno reads values from a soil moisture sensor and activates a mini water pump when the soil becomes too dry. This ensures that plants get watered only when needed, conserving water and reducing manual effort. The system is perfect for both indoor and outdoor potted plants. Easy to assemble and program, it offers a practical introduction to smart agriculture and embedded systems.
