Core Architecture

Data Fusion &
Deterministic Engine

Hazel-Guard operates at the intersection of global meteorological satellite data and hyper-local IoT edge-computing. We eliminate guesswork from agriculture.

The 3-Layer Architecture

How we ingest, fuse, and process data to generate a definitive "Spray or Wait" decision in real-time.

Macro Datasets

NASA POWER & Copernicus Satellite grids. Provides 8-day precipitation forecasts and regional weather models.

Micro IoT Network

Hazel-Guard edge gateways deployed in orchards. Provides live leaf wetness, wind speed, and canopy temperature.

Data Fusion Engine

Calibrates the low-resolution satellite models using our high-resolution ground truth IoT data via localized data fusion algorithms.

Deterministic Decision

Runs against agronomic thresholds to output the exact "Golden Window" for chemical application.

100% Washout Prevented
Agronomic Algorithms

Rainfastness Window Calculation

Chemical pesticides do not work instantly. They require significant time to absorb into the leaf cuticle. If rain falls before this absorption process (Rainfastness) completes, the chemicals are washed directly into the soil.

"Most systemic fungicides and insecticides require a continuous dry period of 4 to 8 hours post-application for optimal leaf cuticle penetration without risk of runoff."

— Based on Willoughby et al. (2024)

Our Processing Scenario:

  • 1

    Our satellite link forecasts rain starting at 18:00.

  • 2

    The engine applies the 8-hour rainfastness offset, closing the viable spraying window exactly at 10:00.

  • 3

    If live IoT wind speed exceeds 3 m/s before 10:00, the system immediately cuts off the window to prevent ILO drift risks.
