The IoT-Based Smart Farming Cycle

The core of IoT in smart agriculture is data collection and analysis. IoT devices gather and process data continuously, enabling farmers to respond quickly to any issues or changes in conditions. The smart farming cycle typically involves four stages:

1. Observation

Sensors collect observational data from crops, livestock, soil, or the atmosphere. This raw data is the foundation for actionable insights.

2. Diagnostics

The collected sensor data is sent to a cloud-hosted IoT platform equipped with predefined decision rules and models. This stage assesses the condition of the monitored subjects and identifies any deficiencies or needs.

3. Decisions

The IoT platform, often augmented by machine learning, evaluates the data to decide if specific actions are necessary. This could involve administering targeted treatments or making strategic adjustments.

4. Action

After the decision is made, the required action is taken—either automatically by connected devices or manually by the farmer. The cycle then starts anew as fresh data is collected.
