A LoRaWAN weather monitoring system, also referred to here as a LoRaWAN-based meteorological monitoring solution, is a wireless system designed to collect, transmit, and manage meteorological data from outdoor or distributed monitoring locations.
It is particularly suitable for projects where monitoring points are spread across a wide area, long-distance cabling is difficult, or mains power and network access are not conveniently available.
In the BGT HYDROMET solution, the complete system architecture consists of:
The meteorological sensor measures environmental parameters such as temperature, humidity, and atmospheric pressure. A LoRaWAN node reads the sensor data through RS485 communication and transmits it wirelessly to a LoRaWAN gateway. The gateway then forwards the data toward the cloud platform or the customer’s own system for remote viewing and management.
This architecture provides a practical way to build a wireless weather monitoring network without relying on long-distance signal cabling.
Why Use LoRaWAN for Weather Monitoring?
Meteorological monitoring is widely used in agriculture, smart cities, environmental monitoring, industrial parks, road weather monitoring, campus monitoring, and remote field projects.
However, many monitoring points are installed outdoors or distributed across multiple locations. In these environments, customers may face several challenges:
Long-distance wiring is difficult or costly.
Mains power may not be available.
Monitoring locations may be widely distributed.
Weather data needs to be viewed remotely.
Multiple monitoring points may be required in different locations.
Customers may already have their own LoRaWAN gateway, network server, or data platform.
Traditional wired weather monitoring systems usually require long-distance cabling, power construction, data acquisition equipment, and on-site integration. This can increase installation cost and make deployment more complicated, especially when multiple monitoring points are involved.
A LoRaWAN-based meteorological monitoring solution addresses these challenges by combining environmental sensing, wireless transmission, gateway communication, and platform access into one system.
What Are the Main Components of a LoRaWAN Weather Monitoring System?
A typical BGT HYDROMET wireless meteorological monitoring solution contains four main parts.
1. Meteorological Sensor
The meteorological sensor is responsible for collecting weather data from the monitoring site.
One typical option is a Louver Box Temperature, Humidity and Pressure Sensor.
This sensor measures:
Temperature
Humidity
Atmospheric pressure
The louver box design helps protect the sensing elements from direct sunlight and rain splash while allowing air circulation for environmental measurement.
The sensor uses RS485 communication and is recommended for use together with a LoRaWAN node for wireless data transmission.
Depending on project requirements, other weather parameters can also be selected when configuring the system.
2. LoRaWAN Node
The LoRaWAN node connects the meteorological sensor to the wireless network.
It collects RS485 sensor data and transmits that data wirelessly through LoRaWAN.
According to project requirements, SN100-WSQ or SN200-WSQ can be selected.
For outdoor monitoring locations where mains power is not available, a solar-powered LoRaWAN node can also be used.
Before confirming the final configuration, sensor compatibility should be checked, including:
RS485 communication
Suitable operating voltage
Low power consumption
Stable data output shortly after power-on
These factors help determine whether the sensor and node can work together properly in a low-power monitoring system.
3. LoRaWAN Gateway
The LoRaWAN gateway receives wireless data from field nodes and forwards it toward the network and data platform.
Indoor or outdoor gateways can be selected according to the actual installation environment.
The gateway is therefore an important communication component between field monitoring devices and the upper-level data system.
4. Data Platform
After the gateway receives data from the LoRaWAN nodes, the data can be uploaded to a cloud platform or customer system.
When using the BGT HYDROMET platform and gateway, customers can access data through a PC dashboard or mobile app.
Depending on the project configuration, the platform can support:
Real-time data viewing
Historical data curves
Device status monitoring
Data export such as Excel or CSV
Alarm notification, if configured
Integration with the customer’s own platform, depending on project requirements
If a customer already has an existing platform, the required communication method, data format, MQTT requirements, and integration details should be confirmed before order confirmation. API functions should also be confirmed according to the actual project scope.
How Does a LoRaWAN Weather Monitoring System Work?
The complete data flow is straightforward.
Step 1: The Meteorological Sensor Collects Weather Data
The meteorological sensor is installed at the monitoring location.
For the standard louver box sensor, the system can collect temperature, humidity, and atmospheric pressure data.
The sensor should generally be installed in an open and unobstructed location, away from buildings, trees, walls, and other obstacles that may affect environmental measurement.
Step 2: The LoRaWAN Node Reads the Sensor Data
The LoRaWAN node communicates with the meteorological sensor through RS485.
It acquires the sensor readings and prepares them for wireless transmission.
Step 3: The Node Sends Data to the LoRaWAN Gateway
The node transmits the collected weather data wirelessly through the LoRaWAN network.
This reduces the need for long-distance signal cabling between monitoring points and the monitoring center.
Step 4: The Gateway Forwards Data to the Platform
The LoRaWAN gateway receives the field data and forwards it toward the cloud platform or customer server.
Step 5: Users View the Data Remotely
Users can then view:
Real-time weather data
Historical records
Data trends
Device status
through a PC dashboard or mobile application.
The full data path can therefore be summarized as:
What Are the Key Benefits of LoRaWAN Weather Monitoring?
No Long-Distance Cabling
Because the system uses LoRaWAN wireless communication, long-distance signal cables are not required between sensors and the monitoring center.
This can reduce wiring requirements and simplify installation, especially for distributed outdoor projects.
Low Power Consumption
The LoRaWAN node is designed for low-power operation.
Depending on site conditions, the system can use:
Battery power
Solar power
External power supply
For applications where the sensor requires longer power-on time or higher power consumption, a solar panel, battery, and charge controller configuration may also be considered.
Long-Range Wireless Transmission
According to the current solution documentation, the typical reference communication distance is approximately 5–10 km in open areas and 1–2 km in urban environments.
Actual transmission range can vary depending on buildings, terrain, antenna height, and surrounding conditions.
Flexible Installation
The system can be deployed in outdoor locations such as farmland, construction sites, parks, roadsides, campuses, reservoirs, industrial areas, and other remote monitoring locations.
Remote Data Access
Weather data can be uploaded to a platform and viewed remotely through a PC dashboard or mobile app.
Users can monitor real-time information, historical trends, and device status without needing to visit every monitoring point.
Scalable Deployment
A LoRaWAN network can support multiple sensor nodes through one gateway.
According to the current BGT HYDROMET solution documentation, one gateway can generally support hundreds of LoRaWAN sensor nodes. The actual capacity should still be confirmed according to project configuration, including the number of nodes, reporting interval, data volume, and site conditions.
For larger projects, additional gateways can be added to expand network coverage.
How Should the LoRaWAN Frequency Band Be Selected?
The supported LoRaWAN frequency plan should be selected according to the destination country or region and local requirements.
The current BGT HYDROMET solution documentation lists common options including:
EU868
US915 / US902
AS923
AU915
The final frequency configuration should be confirmed before shipment.
This is important because the appropriate frequency band depends on where the system will actually be deployed.
How Often Can Weather Data Be Reported?
The reporting interval affects both data refresh speed and power consumption.
For most meteorological monitoring projects, the documentation recommends a 15-minute reporting interval.
A shorter interval, such as five minutes, can be selected when more frequent updates are required. However, shorter reporting intervals increase power consumption and can reduce battery life.
The final reporting interval should therefore be selected according to the monitoring purpose, power supply method, and expected battery life.
Where Can a LoRaWAN Weather Monitoring System Be Used?
The solution is suitable for several outdoor and distributed monitoring applications.
Agricultural Meteorological Monitoring
In farmland, greenhouse surroundings, orchards, and irrigation areas, temperature, humidity, and atmospheric pressure data can help users understand local microclimate conditions and support agricultural management.
Construction Site Environmental Monitoring
At construction sites, meteorological data can support safety management, environmental monitoring, and weather-related work planning.
Smart City Environmental Monitoring
The solution can be used in city parks, streets, campuses, residential communities, and public facilities to collect basic environmental and weather data.
Road and Transportation Weather Monitoring
Weather data can support road condition assessment, early warning, and transportation management, especially in areas affected by fog, rain, temperature changes, or strong wind.
Industrial Park and Factory Area Monitoring
Industrial parks may use distributed weather monitoring for safety management, environmental monitoring, or equipment operation reference.
Remote Field Monitoring
For outdoor locations without convenient power or communication infrastructure, a LoRaWAN-based solution provides a practical wireless monitoring method.
How to Configure a LoRaWAN Weather Monitoring Solution
The final system configuration should not be selected only by product model.
Before configuring a project, several requirements should be confirmed, including:
Required monitoring parameters
Number of monitoring points
Communication distance
Installation environment
Power supply conditions
Gateway installation environment
Platform requirements
Destination country or region
Required LoRaWAN frequency band
The final configuration should be confirmed based on the actual project conditions.
A typical project deployment process includes:
Requirement confirmation
Solution configuration
Pre-configuration before shipment
On-site installation
Network joining and data verification
Operation and maintenance
What Information Should Be Confirmed Before Ordering?
To configure the solution correctly, customers should provide key project information such as:
Installation location and application scenario
Required monitoring parameters
Number of monitoring points
Indoor or outdoor installation
Availability of mains power
Battery or solar power requirements
Expected data reporting interval
Approximate distance between nodes and gateway
Indoor or outdoor gateway requirement
Destination country or region
Required LoRaWAN frequency band
Platform integration requirements
Alarm notification requirements
Local certification or import requirements
Providing this information helps determine the appropriate sensor, LoRaWAN node, gateway, power supply method, and data access configuration.
Conclusion
A LoRaWAN weather monitoring system combines meteorological sensing, data acquisition, wireless communication, gateway transmission, and remote data access into one practical monitoring solution.
Rather than supplying only a standalone sensor, the system connects the meteorological sensor with a LoRaWAN node, gateway, and data platform so that weather data can be collected from outdoor monitoring sites and viewed remotely.
For applications such as agriculture, construction sites, smart cities, industrial parks, road weather monitoring, and remote field monitoring, this architecture can reduce wiring requirements, support battery or solar-powered deployment, and make it easier to expand monitoring points according to project requirements.
The BGT HYDROMET solution is therefore not only a meteorological sensor product, but a complete IoT monitoring package designed to help customers collect, transmit, and manage meteorological data more efficiently.
