Application of Solar-Powered Level Monitoring System in Flue-Cured Tobacco Farmland

1. Background

In a mountainous region in western China, tobacco farmers struggle with irrigation due to poor power infrastructure. To improve water resource efficiency and enable precise irrigation, a solar-powered level monitoring system was deployed to track water levels in real time and send alerts to farmers when action is needed.

2. Solar-Powered Level Monitoring System Components

3. Working Principle

• Solar Charging: The solar panel charges the battery during the day; at night or in cloudy weather, the battery powers the system.
• Level Monitoring: The sensor monitors water levels, and data is transmitted to the cloud via the LoRa module.
• Smart Alert: When levels exceed set thresholds, the app automatically sends alerts to users for irrigation or drainage action.

4. Outcomes and Benefits

5. Extended Applications

• Irrigation Automation: Works with pumps for automatic control
• Flood Alerting: Prevents flooding by monitoring ditches during rainy seasons
• Groundwater Monitoring: Helps avoid over-extraction and protect the ecosystem

6. Conclusion

This solution integrates solar energy, smart sensors, and wireless communication to offer efficient and reliable level monitoring for remote tobacco farmland. It is a practical example of promoting smart agriculture and digital rural development.
