This Valentine’s Day, we’re celebrating a different kind of connection — the seamless integration of spectroscopy with industrial automation.
In modern process engineering, the strongest relationships are built on reliable data, real-time insights, and seamless communication between sensors and control systems.
StellarNet introduces MQTT-enabled spectrometer solutions designed for inline process monitoring, industrial automation, and Industry 4.0 integration. With SMART-Control and StellarPro software, spectrometers become intelligent process sensors that connect effortlessly with SCADA, PLC, and IIoT platforms.
❤️ Built for Connection: Inline Spectroscopy + MQTT Architecture
How do you connect? StellarNet offers two options for MQTT Architecture
1) SMART-Control + MQTT Edge Gateway (Industrial Deployment)
For industrial and remote environments, SMART-Control acts as an intelligent edge gateway:
- Spectrometer connected to SMART-Control via USB
- SMART-Control connected to industrial networks or the internet
- Built-in MQTT host/client publishes spectral and process data to an MQTT broker
- SMART-Control software streams spectroscopic parameters directly to SCADA, PLC, MES, and cloud systems
2) Direct PC-Based MQTT via StellarPro Software (Flexible Deployment)
For laboratory, pilot-scale, and software-driven applications:
- Spectrometer connected directly to Windows, Linux, or macOS systems
- StellarPro software publishes spectroscopic data to an MQTT broker
- No SMART-Control hardware required!
❤️ Real-Time Spectroscopic Intelligence for Process Engineering
StellarNet systems deliver real-time spectral and derived parameters for industrial process monitoring:
❤️Inline Applications Include
- Raman spectroscopy for inline chemical identification and reaction monitoring
- Thin-film thickness measurement for semiconductor and coating processes
- Chemical concentration analysis using absorption and transmission spectroscopy
- Fluorescence intensity and lifetime analysis for biochemical and material characterization
- Radiometer and PAR measurements for optical and environmental monitoring
- Color analysis using spectral and tristimulus data (CIE XYZ, Lab*, chromaticity)
❤️Advanced Process Analytics

- Inline quality control and process optimization
- Spectral fingerprinting and anomaly detection
- Custom process variables and KPIs derived from spectral data
❤️ Customer Application Example
When Multiple Spectrometers Work Together: Remote Algae Monitoring via MQTT
A customer deployed a distributed network of StellarNet spectrometers and radiometers to monitor algae growth and water quality in a remote reservoir.
- Multiple spectrometers and radiometer sensors were installed at different monitoring points
- Each spectrometer was connected to SMART-Control via USB
- SMART-Control units connected via cellular or industrial networks
- SMART-Control publishes PAR and radiometric data to a centralized MQTT broker
- SCADA and cloud analytics platforms subscribe to MQTT topics for real-time monitoring
Key Process Insights
- Correlation of PAR and spectral data with algae growth dynamics
- Real-time absorption and fluorescence signatures of chlorophyll and organic matter
- Chemometric models predicting algae concentration trends
- Early detection of abnormal growth patterns
Value for Process and Environmental Engineers
- Reliable remote monitoring without on-site personnel
- Inline integration of multiple spectrometers into SCADA systems
- Scalable multi-sensor architecture using MQTT
- Unified platform for Raman spectroscopy, radiometry, and chemometric analytics
This architecture is directly applicable to industrial process monitoring, water treatment systems, chemical processing, semiconductor manufacturing, and advanced material characterization.
