System Overview
RaiSmart uses soil moisture as the primary signal to reduce dry/wet spots and avoid unnecessary pumping.
System Architecture
• Sensors → ESP32 (logic) → Relay → Pump → Irrigation
• Solar → Charge Controller → 12V Battery → System
• Mobile dashboard (pilot monitoring)
Solar-ready power supports an ESP32 controller that triggers the pump via a relay based on soil-moisture thresholds.
Operating flow (5 steps)
• Sense: soil moisture + context (T/H, light)
• Decide: compare to thresholds / target band
• Water: run pump in controlled cycles
• Verify: re-check and stop at target level
• Log & improve (pilot): record events to refine thresholds; manual override if needed
Signals we use (3)
• Soil moisture: primary decision signal (handles variability across rows)
• Temperature/Humidity: weather context
• Light: time-of-day context
Impact link
Targets measurable outcomes: less labor time, improved moisture consistency, and reduced pump runtime (waste proxy).
