Smart farming
for Thai rice growers
with AI

Advancing Thai rice farming with AI

RiceGuard Sentinel brings IoT and AI to Thai farmers for precise use of water, fertiliser, and pest care — a research effort exploring how sensing and machine learning can support rice farmers, not replace their judgement.

01The R&D Story · The R&D Story

From a real field to a redesign

From a real field to a redesign — Gen 3 → Gen 4

This isn't a lab product — every Gen 4 decision traces to something the field taught us.

Gen 3 · Songkhla 2026

What the data told us

9.1%Gen 3 average uptime
across the first wet season
  • Electronics flooded as water levels rose in the paddy
  • Battery ran flat during several days of continuous rain
  • Intermittent data gaps broke the continuity of analysis

    Gen 3 deployed at Ranot, Songkhla

    A 36-rai prototype station collecting real data through the first wet season

  2. Problems found
    Flooding · submerged electronics · dead battery

    Uptime dropped to 9.1% — data lost across many periods

  3. The fix
    Hexagonal prism mast + raised foundation

    Electronics moved up high, IP68-sealed throughout

02How it works · The 4-Layer Data Pipeline

From the field to the farmer's hand

From the field to the farmer's hand, in four steps

01 · Field

Edge acquisition

Sensors + images, timestamped and pre-filtered right on the device.

02 · Edge

Edge inference

Urgent decisions — pest and flood alerts — happen instantly, no cloud needed.

03 · Cloud

Cloud & fusion

Deep analysis fuses sensor and image data and retrains the models.

04 · Farmer

Presentation

Human-readable insights and alerts via app, SMS, and dashboard.
