Architecture Philosophy: System Architecture Rule: One product, two hardware units. The Main Hub is the farm controller; Sensor Hub stations are companion sensing units only — they do not control actuators directly.
Real-time Data Flow & Connectivity
Sensor Hub
ESP32-S3 gathers temp, CO₂, NH₃, humidity telemetry.
Wi-Fi / ESP32-S3
MQTT over TLS
Secure, encrypted local message transmission.
TLS (Port 8883)
Main Hub Controller
Fuses data, runs local PID logic with 100% offline uptime.
ARM64 Gateway
Nabd Cloud & Mobile
SaaS platform for remote monitoring & control.
LTE / HTTPS WAN
Main Hub Controller Operations
- Main controller for farm/house climate, feed, lighting, local HMI, fail-safes, and logging.
- Fuses multi-station telemetry into room Golden Values and drives physical actuators.
- Continues full offline execution if the WAN cloud link is lost.
Sensor Hub Stations Deployment
- Positioned in rooms: N stations per room based on size & layout.
- ESP32-S3 MCU collects environmental telemetry and supports local calibration workflows.
- Transmits telemetry wirelessly over Wi-Fi + MQTT/TLS (Port 8883).
Deployment Scope
- 1 Main Hub per farm iteration.
- Supports multiple poultry rooms per farm.
- N Sensor Hubs per room sized dynamically.
Executive Summary
- Product: ASF Hub System (Automated Smart Farm).
- Main Hub: ARM64 CM4-class edge controller.
- Sensor Hub: ESP32-S3 room station.
Value Proposition
An industrial on-farm automation system combining a Main Hub controller with wireless Sensor Hub stations that measure room climate, calibrate sensors, and feed fused 'Golden Values' into automated climate, feed, water, and lighting control — with offline-first safety and cloud + mobile access.
Core Functional Modules
Climate & Environment
- Temp, humidity, CO₂, NH₃, air quality, ventilation management.
- Multi-station Sensor Hub fusion into room Golden Values on Main Hub.
- Actuators: fans, heaters, cooling pads, foggers, inlets/curtains.
Feeding, Water & Light
- Feeder & drinker control; schedules driven by Control Engine.
- Silo weighing & pulse water meter integration.
- Automated lighting programs by flock age with Lux measurement.
Flock Operations & HMI
- Flock lifecycle tracking: entry, mortality, weight, exit.
- Local HMI dashboard on Main Hub (10.1" touchscreen).
- On-demand camera streaming via cloud.
Mobile Application Module
- Remote monitoring & control via Nabd Cloud (not direct LAN).
- Live telemetry, alarms, setpoints, manual overrides.
- Push notifications for critical alarms.
