Higher Sensor Coverage vs Lower Technology Cost
Concentrate permanent sensors at high-variability critical points and use mobile or remote sensing elsewhere, ensuring all collected data is processed under a lawful GDPR basis with proportionate retention.

Business Context
Sensors can provide detailed information about soil conditions, machinery, crops, livestock, weather, irrigation, storage, and environmental performance. Increasing sensor density can improve visibility and detect localized changes earlier. However, each additional device introduces acquisition, installation, communication, calibration, maintenance, energy, and data-management costs. Sparse sensing reduces these costs but may fail to capture important variability.
Agriculture TRIZ Resolution
Sensor coverage should reflect spatial and temporal variability rather than using identical measurement density everywhere. Permanent sensors can be concentrated at critical locations, while mobile sensors, machinery-mounted devices, drones, remote sensing, and representative sampling provide broader periodic coverage. Analytical models can interpolate between measurements where conditions are sufficiently predictable.
Applicable TRIZ Principles
Principle 1 – Segmentation assigns different sensing intensity according to monitoring value.
Principle 28 – Mechanics Substitution replaces some fixed physical measurement points with remote or mobile sensing.
Principle 23 – Feedback increases measurement intensity when detected conditions justify additional observation.
Expected Outcome
Better production visibility
Lower sensing infrastructure cost
Improved monitoring coverage
Higher information value per measurement
Decision Indicators
Early indicators include:
Sensor networks expand faster than their contribution to decisions.
Large numbers of devices monitor highly stable conditions.
Important variability remains undetected despite extensive sensing.
Sensor maintenance becomes a significant operational workload.
Every new monitoring requirement results in additional permanent hardware.
These indicators suggest that sensing architecture should combine permanent, mobile, and indirect measurement.
