Akhil AdariBuild a production-ready IoT + AI platform for Spirulina raceway pond cultivation. IMPORTANT: This is NOT just a pilot dashboard. Start with a prototype, but design the architecture for REAL-TIME operation of 2 commercial raceway ponds after validation, with future scaling to many ponds and farms without rebuilding the core system. GOAL Build an "AI Spirulina Cultivation Intelligence Platform": Sensors → IoT Gateway → Internet → FastAPI → PostgreSQL → AI → Safety Engine → React Dashboard → Alerts → Human Approval → Future Automation. Initial deployment: - 1 farm - 2 raceway ponds - Independent sensors/data for each pond - Real-time monitoring - AI prediction/recommendations - Alerts - Human override - Future equipment control HARDWARE Each pond should support: - pH - Water temperature - EC/conductivity - Dissolved oxygen (DO) - Light intensity - Water level Future-ready: - ORP - Flow rate - Aerator/pump status - Weather - Ambient temperature/humidity - Solar radiation - Rainfall - Biomass/optical density - Nutrient/dosing data Use ESP32-S3 or industrial IoT gateway. Prefer RS485/Modbus or 4–20mA for industrial sensors. Avoid long analog wiring where possible. Include: - IP-rated enclosure - Waterproof connectors - Surge protection - Electrical isolation - Stable power - Backup power - Watchdog - Local data storage - OTA firmware updates - Future solar support Make sensor sampling and transmission intervals configurable. DATA FLOW Pond sensors → ESP32/IoT Gateway → MQTT/HTTPS → FastAPI → Data validation → PostgreSQL/TimescaleDB → Real-time events → React dashboard → AI engine → Safety engine → Alerts/recommendations → Future equipment control If internet fails, the gateway must continue collecting data locally and synchronize when connectivity returns. DATABASE Design schemas for: Organizations, Farms, Ponds, Devices, Sensors, Sensor Readings, Calibration, Sensor Health, Cultivation Batches, Strains, Water Characteristics, Nutrients, Weather, Biomass, Harvests, Protein %, Phycocyanin, AI Predictions, AI Recommendations, Alerts, Safety Thresholds, Human Approvals, Equipment, Automation Events and Audit Logs. Every reading must contain: farm_id, pond_id, device_id, sensor_id, timestamp, value, unit and quality status. DATA QUALITY Never assume sensor data is correct. Detect: - Missing readings - Disconnected sensors - Stuck values - Impossible values - Spikes/drops - Calibration drift - Communication failure - Abnormal rate of change - Out-of-range values Status: VALID / SUSPECT / INVALID / MISSING / CALIBRATION_REQUIRED. AI must not use invalid/suspicious readings. CALIBRATION Store: sensor ID, installation date, calibration date, calibration method/reference, result, next calibration date and calibration history. Show calibration reminders. SAFETY ENGINE AI must NEVER directly control equipment. For important parameters create configurable: - Optimal range - Warning range - Critical range - Absolute minimum - Absolute maximum - Maximum rate of change Values must be scientifically validated. Architecture: Sensor → Validation → AI → Safety Engine → Human Approval/Automation → Equipment If an absolute limit is reached: - Stop automation - Critical alert - Notify human - Require human inspection - Log the event AI cannot override safety limits. AI Do NOT create a completely separate model for every customer. Use: Scientific/Foundation Model + Farm-specific calibration + Farm historical data Inputs can include: pH, temperature, EC, DO, light, weather, water chemistry, nutrients, strain, pond geometry, biomass and cultivation history. Outputs: - Growth prediction - Biomass prediction - Productivity prediction - Risk prediction - Trend prediction - Recommendations - Confidence score Use: published scientific literature + controlled experiments + pilot data + customer farm data. For a new farm/climate with limited data: - Use scientific baseline - Show confidence - Start in Shadow Mode - Collect actual results - Compare prediction vs actual - Gradually calibrate to the farm - Detect conditions outside the validated model domain Never make high-confidence predictions outside validated conditions. SHADOW MODE AI predicts/recommends but does not control equipment. Store: Prediction → Actual result → Error → Model performance. Only after validation should human-approved recommendations or automation be enabled. DASHBOARD Use React + TypeScript + Material UI. Farm Overview: Pond 1 and Pond 2 with: - pH - Temperature - EC - DO - Light - Water level - Biomass if available - Current batch - Sensor health - AI confidence - Alerts Status: GREEN = optimal YELLOW = warning ORANGE = critical RED = unsafe GREY = unavailable Pond Detail page: - Real-time values - 24h/7d/30d charts - Historical batches - pH - Temperature - EC - DO - Light - Biomass - Growth - Weather Allow Pond 1 vs Pond 2 comparison. AI INSIGHTS Show: "pH has increased for 6 hours." "Current trend may enter warning zone in approximately X hours." "Predicted biomass growth: X%." "Confidence: X%." "Recommended action: Review cultivation conditions." Clearly distinguish measured data from predictions. ALERTS Support dashboard + email, with future SMS/WhatsApp/mobile support. Levels: INFO / WARNING / CRITICAL / EMERGENCY Alert for: - Parameter approaching limit - Rapid change - Sensor failure - Calibration due - Internet failure - Low AI confidence - Predicted safety-limit crossing HUMAN-IN-THE-LOOP For each AI recommendation show: Current value, trend, prediction, confidence, recommendation and reason. Actions: APPROVE / REJECT / SNOOZE / REQUEST REVIEW Record user, timestamp, action, reason and outcome. FUTURE AUTOMATION Support future: - Aerators - Pumps - Valves - Dosing pumps - Mixing systems Architecture: AI → Safety Engine → Human Approval → Control Gateway → PLC/Relay → Equipment Keep automation disabled initially. TWO-POND ARCHITECTURE Pond 1 and Pond 2 must have independent: - Sensor IDs - Devices - Data streams - Cultivation batches - Alerts - AI predictions - History Allow comparison of growth, productivity, environmental conditions and outcomes. MULTI-FARM READY Design as multi-tenant SaaS: Organization → Farm → Ponds → Gateways → Sensors Roles: Super Admin, Farm Owner, Manager, Operator, Scientist, Viewer. Implement tenant isolation and RBAC. DEVICE MANAGEMENT Show: Device ID, online/offline, heartbeat, firmware, signal, power, sensor status, synchronization and errors. Support registration, configuration, sampling intervals and OTA firmware. OFFLINE MODE Gateway stores readings locally during internet failure and synchronizes later. Show last synchronization time. TECHNOLOGY Frontend: React + TypeScript + Material UI + Recharts/Chart.js Backend: Python + FastAPI + Pydantic + SQLAlchemy Database: PostgreSQL + TimescaleDB IoT: ESP32-S3/industrial gateway + RS485/Modbus + MQTT/HTTPS Infrastructure: Docker/Docker Compose initially; cloud-ready. AI: Python + scikit-learn initially, PyTorch when needed, MLflow. Do not introduce Kubernetes initially. SECURITY JWT, RBAC, tenant isolation, HTTPS, device authentication, secure credentials, validation, rate limiting and audit logs. Devices must not submit data for another farm. DEVELOPMENT 1.

Watch your Spirulina ponds think in real time
Sensors stream pH, temperature, EC, dissolved oxygen, light intensity and water level from Pond 1 and Pond 2 every few seconds. The AI engine turns that stream into growth predictions, risk signals and human-approved recommendations — explore the model below.
Hover or focus a sensor marker, or use the buttons below, to inspect a live reading.
The Challenge in Spirulina Cultivation
Commercial raceway ponds are unforgiving. Small, unnoticed shifts in water chemistry compound quickly — and today, most farms are still fighting them with clipboards instead of data.
Manual Monitoring
Operators still walk pond-to-pond with handheld meters, checking pH, temperature and EC by hand — a process that is slow, inconsistent, and impossible to run around the clock.
Delayed Insights
By the time a spreadsheet reveals a drifting pH or falling dissolved oxygen, hours have already passed — often too late to prevent a culture crash.
Operator Workload
Every reading, log entry and calibration check adds to an already stretched operator workload, leaving little time for the strain science that actually grows better Spirulina.
Core Capabilities
Everything a commercial raceway pond operation needs, from sensor-level data quality to human-approved AI recommendations, built to scale from 2 ponds to many farms without rebuilding the core system.
