Story
Keep your plants healthy with this Arduino-based Smart Plant Care Assistant! This device monitors your plant’s soil moisture, light intensity, and ambient temperature, alerting you when your plant needs water or more light. Notifications are sent through an LED and buzzer, making plant care easy and fun.
This project is beginner-friendly, yet visually appealing, perfect for plant lovers and Arduino enthusiasts alike.
Features:
-
Soil Moisture Monitoring: Alerts you when your plant needs watering.
-
Light Monitoring: Detects low light conditions for optimal plant growth.
-
