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.
