Firebase Realtime Database schema for an IoT incubator monitoring system organizes user management, device registry, telemetry streams, and control logic across eight root collections. Live sensor data flows from devices through liveData nodes capturing temperature, humidity, and actuator states, while historicalLogs archives timestamped readings for trend analysis. Control commands with PID tuning parameters enable precise environmental regulation, and alerts track threshold violations with resolution status. This schema demonstrates Firebase's denormalized data modeling for sub-second synchronization across mobile and web dashboards monitoring agricultural or laboratory incubators.
