Smart Water Irrigation System
Efficient water management using IoT technology. Auto-schedule watering based on soil moisture, weather, and plant needs.
What is Smart Water Irrigation?
KoMoMi’s Smart Water Irrigation transforms farming from “experience-based watering” to “data-driven irrigation” — using IoT sensors to measure real-time soil moisture, AI algorithms to calculate optimal water requirements, and automatic control of pumps and valves.
“After testing on a 50-rai durian farm in Rayong, we achieved 30% water savings while increasing yield by 15%.” — KoMoMi Field Trial 2025
Key Features
🌡️ Capacitance Soil Moisture Sensor
- Measures at root-depth levels (10cm, 20cm, 30cm)
- ±2% accuracy, rust-free (unlike Resistance sensors)
- Over 5-year lifespan in agricultural environments
📱 Mobile App Control (Blynk / ThingsBoard)
- Turn pumps on/off from anywhere in the world
- Monitor system status in real-time 24/7
- Set automatic watering schedules by time or conditions
🤖 AI Water Calculation
- Analyzes soil moisture + weather forecast + plant growth stage
- Recommends optimal daily water amount
- Auto-adjusts by season
🔔 Smart Alerts
- Line Notify when soil moisture drops below threshold
- Alerts when pump malfunctions
- Alerts when tank/water source is low
🌧️ Rain Data Integration
- Receives weather forecast from Weather API
- If rain predicted → auto-postpones irrigation
- Prevents over-watering and root flooding
Benefits for Farmers
💰 Reduce Water Costs by 20-30%
Water based on actual plant needs, not fixed schedules or intuition.
🌱 Increase Yield by 10-15%
Plants receive optimal water at the right time → less stress → better production.
