AxonSENSE
Industrial IoT (Internet of Things) and Smart Environmental Monitoring Ecosystem
What is AxonSense? What Does It Do?
We make your home, villa, rooms, garden, greenhouse, and store smart using Internet of Things (IoT) technology. It is an advanced automation ecosystem that allows you to monitor and manage your living and working spaces from anywhere in the world.
System Architecture and Software Infrastructure
AxonSense is not just an ordinary sensor reader. It features a distributed cloud architecture that establishes asynchronous, bidirectional, and encrypted communication between devices (Edge) and the Server (Cloud). Thanks to its custom-developed Gateway structure, it can process data from thousands of devices in real-time.
Cloud Gateway & SignalR Hub
ESP32 hardware transmits its data directly to the GatewayHub instead of the main server. Thanks to the WebSockets infrastructure, physical relay statuses and sensor data are synchronized with the web interface in milliseconds (Real-time).
Anti-IDOR & HMAC-SHA256
Every data packet from the endpoints is signed with the HMAC-SHA256 algorithm using the Device Secret Key. The system detects unsigned or unauthorized access (IDOR) and rejects it at the network layer.
I2C & Hardware Synchronization
The 8-channel relay module on the device is controlled by the PCF8574 I2C IC. The ConcurrentDictionary-based RAM memory on the server verifies the physical pin status on the hardware (Physical Confirmation) to prevent inconsistencies.
Data Flusher & Bulk Insert
Thousands of sensor records arriving per second are not written directly to SQL. With DataFlusherService (BackgroundService), data is collected in the RAM (MemoryCache) pool and asynchronously transferred to the database periodically (Bulk Insert).
Smart Anomaly Detection and WhatsApp Alarm System
The SensorControlService analyzes raw data from the hardware 24/7 via ADS1115 (16-bit ADC) and logarithmic calculations converted into PPM / Percentage values.
- Life-Threatening (Emergency) Flag logic that bypasses the timer for critical gases (CO, LPG, Smoke, Hydrogen, Natural Gas).
- Zero-latency dynamic reporting to administrators' WhatsApp numbers with UltraMsg API integration.
- MAC address-based Cooldown (Timeout Tolerance) algorithm to prevent system spam.
Hardware Design and R&D Process
Snapshots from the electronic circuit design and testing environment compliant with industrial standards.
PWA Supported User Interface (Mobile Devices)
The platform features a secure interface designed according to "Glassmorphism" UI rules on ASP.NET Core MVC, supported by multi-language (Localization) and encrypted Cookie-Auth.
Big Data and Trend Analysis
Hourly sensor data (Temperature, MQ135, MQ2, VOC, etc.) accumulated on SQL Server is grouped with LINQ queries and presented to the user via the Chart.js library.
A smart ecosystem designed end-to-end with scalable system architecture, industrial hardware integration, and distributed data processing (Gateway) infrastructure in the Internet of Things (IoT) standards of our era.
