Weather Stations
Track temperature, humidity, rainfall, wind speed, and solar radiation. Local weather data improves prediction accuracy compared to regional forecasts.
Plant Health Sensors
Monitor chlorophyll content, leaf temperature, and plant water stress through various optical and thermal measurements.
Livestock Monitoring
Track animal health, location, feeding patterns, and reproductive cycles through wearable sensors and monitoring systems.
Equipment Sensors
Monitor machinery performance, fuel consumption, maintenance needs, and operational efficiency.
Data Collection and Transmission
Wireless Networks
Modern agricultural IoT relies on various wireless technologies:
- LoRaWAN: Long-range, low-power networks ideal for large farming operations
- Cellular Networks: 4G/5G connectivity for high-data applications
