An IoT-based automatic plant watering system that monitors soil moisture and waters plants as needed. The system includes a mobile app that enables remote monitoring and manual control of watering operations.
This project aims to make plant care hassle-free using smart technology. Built using a NodeMCU microcontroller and soil moisture sensor, the system can:
- Detect real-time soil moisture levels
- Automatically trigger watering when the soil is dry
- Allow manual control via a custom-built Android app
- Operate remotely using Firebase and Wi-Fi connectivity
- 🌡️ Real-time soil moisture monitoring
- 🚿 Automatic and manual watering modes
- 📲 Android app for remote control and monitoring
- ☁️ Cloud-based status syncing using Firebase
- 🔋 Low-power operation for extended use
