Temperature and humidity are two of the most important environmental parameters in many industrial facilities. In a factory, warehouse, cleanroom, server room, or cold-storage area, unstable environmental conditions can affect equipment reliability, product quality, and operational continuity.
The challenge is that manual inspection only provides isolated readings. For facilities with multiple monitoring points, a more effective approach is to connect field sensors to a centralized SCADA platform.
A practical architecture can be built around AT-THMS 3.1 + ATSCADA.
1. The Challenge: Distributed Environmental Monitoring
Imagine a production facility with temperature and humidity sensors installed in several areas.
Without centralized monitoring, operators may need to:
- Check each location manually
- Record measurements periodically
- Compare readings from different areas
- Identify abnormal conditions after they occur
- Prepare historical reports manually
This approach becomes inefficient as the number of monitoring points increases.
A connected architecture solves this by allowing field devices to continuously provide environmental data to a centralized monitoring platform.
2. AT-THMS 3.1 as the Field Measurement Device
The AT-THMS 3.1 temperature and humidity sensor provides real-time temperature and relative humidity measurement.
The device is designed for industrial monitoring and includes RS485 Modbus RTU communication, allowing measurement data to be integrated into PLC, SCADA, and BMS systems.
Key capabilities include:
- Temperature measurement from -40°C to +125°C
- Humidity measurement from 0–100% RH
- 0.1°C and 0.1% RH resolution
- RS485 Modbus RTU communication
- Two independent relay outputs
- Local LED display
- Industrial installation options
This makes the sensor useful not only as a standalone display but also as a field-level data source for a larger automation architecture.
3. Connecting the Field Layer to SCADA
The basic architecture is straightforward:
AT-THMS 3.1 Sensors

│ RS485 Modbus RTU

ATSCADA Platform

├── Real-Time Monitoring
├── Alarm Management
├── Historical Data
└── Reports
Multiple AT-THMS 3.1 devices can be deployed across different areas. Their measurements can then be collected and visualized through the SCADA system.
This changes the monitoring workflow from:
Measure → Record manually → Review later
to:
Measure → Transmit → Monitor → Detect → Respond → Record
4. Centralized Monitoring with ATSCADA
The ATSCADA temperature and humidity monitoring software provides the centralized monitoring layer.
Instead of checking every sensor individually, operators can view multiple monitoring points from one interface.
Typical functions include:
- Real-time temperature monitoring
- Real-time humidity monitoring
- Multi-area visualization
- Alarm management
- Historical trends
- Data reporting
- Excel report export
- Remote monitoring capabilities
This is particularly useful when environmental conditions need to be monitored continuously rather than checked only during routine inspections.
5. Why Historical Data Matters
A real-time value tells an operator what is happening now. Historical data provides the context needed to understand what happened over time.
For example, a facility may discover that humidity repeatedly rises during a particular production period. By reviewing historical trends, engineers can investigate whether the cause is related to ventilation, cooling, production processes, or other environmental factors.
Historical records can therefore support:
- Quality-control analysis
- Maintenance investigations
- Environmental documentation
- Production optimization
- Internal reporting
- Long-term process improvement
6. Faster Response to Abnormal Conditions
Monitoring becomes more valuable when the system can identify abnormal conditions quickly.
When temperature or humidity exceeds a predefined threshold, the monitoring system can generate an alarm. Depending on the project configuration, alarms can be used to notify operators or trigger external equipment.
The relay outputs available on AT-THMS 3.1 can also be configured for applications such as warning lights, fans, ventilation equipment, or other control devices.
The result is a practical control loop:
Environmental Change → Detection → Alarm → Operator Response
This can reduce dependence on periodic manual inspection.
7. Where Can This Architecture Be Used?
The combination of field measurement and centralized SCADA monitoring is suitable for many industrial environments:
Manufacturing Facilities
Monitor production areas, equipment rooms, and environmental conditions that may influence manufacturing processes.
Warehouses
Track temperature and humidity across storage areas and identify environmental changes that may affect stored products.
Server Rooms and Data Centers
Monitor environmental conditions around critical IT infrastructure and cooling systems.
Cleanrooms
Maintain continuous records of environmental conditions where stable temperature and humidity are important.
Cold Storage
Monitor environmental parameters continuously and identify abnormal conditions before they become larger operational problems.
8. The Main Advantage: A Scalable Architecture
The important point is that this is not simply a temperature and humidity sensor combined with software.
It is a field-to-SCADA monitoring architecture:
AT-THMS 3.1
→ Accurate environmental measurement
RS485 Modbus RTU
→ Industrial communication
ATSCADA
→ Centralized monitoring, alarms, historical data, and reporting
As monitoring requirements increase, additional field devices and monitoring points can be incorporated into the overall architecture.
9. Planning an Industrial Monitoring Project?
For an actual deployment, the configuration should be selected based on:
- Number of monitoring points
- Temperature and humidity range
- Installation environment
- Required communication protocol
- Alarm requirements
- Data logging requirements
- Reporting requirements
- Existing PLC/SCADA/BMS infrastructure
If you are developing a temperature and humidity monitoring system for a factory, warehouse, data center, cleanroom, or storage facility, these parameters can be used to determine the appropriate system architecture and prepare an RFQ.
The goal is not simply to collect environmental measurements. The goal is to turn those measurements into real-time information that operators can monitor, analyze, and act on.
