Short Summary

This paper presents a low-cost satellite positioning-based precision irrigation and crop health monitoring system using an ESP32 microcontroller, soil-moisture sensor, DHT22 temperature and relative-humidity sensor, light-intensity sensor, NPK sensor, pH sensor, and NEO-6 GPS receiver. The system demonstrates a 29.3% reduction in water consumption compared with fixed-time irrigation.

Objective

• Investigate the feasibility of using satellite positioning for precision agriculture.
• Develop an IoT-based precision irrigation system that integrates soil moisture, temperature, relative humidity, light intensity, NPK, pH, and GPS measurements.

Study Configuration

• Spatial Scale: Field level (meter-level positioning)
• Temporal Scale: Real-time monitoring

Methodology and Data

• Models used: ESP32 microcontroller
• Data sources: Satellite positioning (NEO-6 GPS), soil-moisture sensor, DHT22 temperature and relative-humidity sensor, light-intensity sensor, NPK sensor, pH sensor

Main Results

• The system demonstrated a 29.3% reduction in water consumption compared with fixed-time irrigation.
• The NEO-6 GPS receiver provided meter-level positioning accuracy for basic field geo-tagging and spatial zoning.

Contributions

• This study presents a low-cost satellite positioning-based precision irrigation and crop health monitoring system that integrates soil moisture, temperature, relative humidity, light intensity, NPK, pH, and GPS measurements.
• The system provides a practical and relatively inexpensive approach for precision agriculture, particularly for small- and medium-scale farms.

Funding

• This research was funded by the National Space Research & Development Agency (NASRDA), Abuja, Nigeria.
