v2.0.0-alpha

Release v2.0.0-alpha

This is the initial release of the IoT Plant Monitoring System. This version includes:

• ESP32 Integration: Connects to Wi-Fi and AWS IoT Core for data communication.
• Sensor Data Collection: Reads and publishes data from a DHT11 sensor (temperature and humidity) and a soil moisture sensor.
• Cloud Connectivity: Utilizes MQTT for communication with AWS IoT Core, allowing real-time monitoring and data publishing.
• Time Synchronization: Connects to NTP servers to provide accurate timestamps for data logs.

Features:

• Real-time monitoring of plant health.
• Data publishing to AWS IoT Core.
• Time synchronization with NTP servers.
• Integration with DHT11 and soil moisture sensors.

Setup Instructions:

1. Install Libraries: Use PlatformIO to handle library dependencies.
2. Update Credentials: Modify secrets.h to include your AWS IoT and Wi-Fi credentials.
3. Configure Time Zone: Set the TIME_ZONE in config.h.
4. Upload Code: Use PlatformIO to upload main.cpp to your ESP32 board.

Troubleshooting:

• Wi-Fi Connection: Ensure correct credentials and good network coverage.
• NTP Synchronization: Check internet connectivity and NTP server status.
• AWS IoT Connectivity: Verify AWS IoT configuration, including endpoint and credentials.
