Soil and Air Temperature Humidity Sensor with LoRaWAN Collector: A Complete Guide for Remote Agriculture Monitoring

Monitoring both soil temperature and humidity and air temperature and humidity gives agricultural operators a more complete picture of crop-growing conditions. A soil and air temperature humidity sensor connected to a LoRaWAN collector can collect field data, transmit it wirelessly over a low-power network, and integrate the measurements with a remote monitoring platform.

For farms, greenhouses, orchards, agricultural research stations, and environmental monitoring projects, this architecture can reduce field wiring while enabling centralized and remote access to sensor data. Honde Technology provides customizable IoT sensing and wireless communication solutions that can combine soil sensors, air sensors, LoRa/LoRaWAN collectors, gateways, cloud software, and MQTT communication.

1. What Is a Soil and Air Temperature Humidity Monitoring System?

A soil and air temperature humidity monitoring system measures environmental conditions both below and above the ground.

The basic concept is:

Soil Sensor + Air Sensor → LoRaWAN Collector → LoRaWAN Gateway → MQTT/Cloud Server → Remote Monitoring

Unlike a single soil sensor, this architecture allows users to compare the conditions around the crop with the conditions inside the root zone.

Key Monitoring Parameters

Monitoring Area	Typical Parameters	Application Value
Soil	Soil Temperature	Root-zone temperature monitoring
Soil	Soil Moisture	Irrigation management
Air	Air Temperature	Crop growth and climate monitoring
Air	Air Humidity	Humidity and disease-risk assessment
Communication	LoRa/LoRaWAN	Long-range wireless transmission
Data	MQTT / Cloud	Remote monitoring and integration

The combination of soil and atmospheric measurements is particularly useful because irrigation decisions should not be based only on soil moisture. Weather conditions, air temperature, and humidity can also affect evaporation, crop transpiration, and water demand.

2. Why Monitor Soil and Air Conditions Together?

Soil Temperature and Moisture Affect the Root Zone

Soil moisture is one of the most important parameters for irrigation management.

When soil moisture is too low:

Crops can experience water stress
Nutrient uptake may decrease
Irrigation demand increases
Crop growth can be affected

When soil moisture remains excessively high:

Root-zone oxygen availability can decrease
Waterlogging may occur
Nutrient loss can increase
Root diseases may become more likely

Soil temperature is also important because root activity and microbial processes are influenced by temperature.

Therefore, measuring soil temperature + soil moisture provides more information than measuring either parameter independently.

Air Temperature and Humidity Provide the Environmental Context

The atmosphere surrounding the crop influences evaporation, transpiration, ventilation, and greenhouse management.

For example:

High air temperature + low air humidity + low soil moisture

may indicate a higher irrigation requirement.

Conversely:

High air humidity + high soil moisture

may indicate an environment where ventilation, drainage, or irrigation adjustment should be considered.

This is why combining soil and air monitoring creates a more useful dataset for precision agriculture.

3. How Does a LoRaWAN Soil and Air Monitoring System Work?

A typical Honde-style architecture can be divided into four layers.

Layer 1: Sensors

The sensors collect field measurements.

Typical measurements include:

Soil temperature
Soil moisture
Air temperature
Air humidity

Depending on the project, additional soil or environmental sensors can also be integrated.

Layer 2: LoRaWAN Collector

The LoRaWAN collector acts as the communication hub between field sensors and the wireless network.

Instead of installing long communication cables throughout a farm, sensor data can be collected and transmitted wirelessly.

This is especially useful for:

Large agricultural fields
Orchards
Greenhouses
Remote monitoring stations
Research plots
Distributed sensor networks

Layer 3: LoRaWAN Gateway

The gateway receives wireless data from field devices and forwards the information to the backend system.

A gateway can connect the field network to the Internet using communication options such as:

4G
WiFi
Ethernet

Layer 4: Cloud Server and Software

After the data reaches the server, users can access:

Real-time data
Historical data
Data charts
Alarm notifications
Device status
Remote monitoring dashboards

Honde’s published agricultural monitoring architecture similarly uses field sensors, LoRa communication, a gateway, and MQTT/cloud transmission to create an end-to-end monitoring network.

4. LoRaWAN vs Traditional Wired Sensor Networks

One of the main reasons to use LoRaWAN is to reduce the complexity of deploying distributed sensors.

Feature	Traditional Wired System	LoRaWAN System
Field Cabling	More cabling required	Wireless sensor communication
Deployment	More installation work	Easier distributed deployment
Large Fields	Cable routing can be difficult	Suitable for distributed nodes
Scalability	Additional wiring may be required	Additional wireless nodes can be added
Remote Monitoring	Requires communication infrastructure	Gateway can connect to cloud
Maintenance	Cable damage can be an issue	Reduced field communication wiring

For a small installation, a wired RS485 sensor may be sufficient.

For a large agricultural project with many monitoring points, however, a LoRaWAN architecture can offer a more flexible deployment model.

5. GPRS/4G/WiFi/LoRa/LoRaWAN and MQTT Connectivity

For commercial IoT projects, sensor measurement is only one part of the solution.

The more important question is:

How does the sensor data reach the customer’s monitoring platform?

Honde IoT monitoring solutions support different communication architectures depending on project requirements.

The system can be designed around:

GPRS/4G wireless communication
WiFi
LoRa
LoRaWAN
MQTT
JSON data format
Cloud server and software
Alarm relay system

This makes the system suitable for projects where sensor data needs to be connected to an existing IoT platform rather than viewed only locally.

Honde’s existing system documentation describes MQTT transmission from a field gateway to a remote server and supports real-time and historical monitoring.

6. Why MQTT Is Important for Agricultural IoT

MQTT (Message Queuing Telemetry Transport) is widely used in IoT systems because it is designed for efficient machine-to-machine communication.

For agricultural monitoring, the architecture can be represented as:

Sensor → LoRaWAN Collector → Gateway → MQTT → Cloud Server → Dashboard

This separates the sensing layer from the cloud application.

As a result, the customer can potentially integrate sensor data with:

Agricultural management software
IoT platforms
Cloud dashboards
Data analysis systems
Automatic irrigation systems
Greenhouse control systems

Honde’s published agricultural IoT architecture specifically describes MQTT as the communication protocol between field monitoring equipment and cloud/server systems.

7. Real-Time Data, Historical Data and Alarm Relay

A professional monitoring system should not only collect data.

It should help users understand the data and take action.

Real-Time Monitoring

Users can monitor current:

Soil temperature
Soil moisture
Air temperature
Air humidity

This helps operators understand current field conditions without physically visiting every sensor location.

Historical Data

Historical data allows users to identify:

Daily temperature changes
Soil moisture trends
Seasonal variations
Irrigation effects
Long-term environmental patterns

Alarm Relay

For applications requiring automatic responses, an alarm relay can be integrated into the monitoring architecture.

For example:

Low Soil Moisture → Alarm → Relay Output → Irrigation Equipment

or:

High Temperature → Alarm → Relay Output → Ventilation System

Honde’s LoRaWAN agricultural architecture describes relay output control as an option for triggering equipment such as irrigation pumps or ventilation fans according to monitoring conditions.

8. Main Applications of Soil and Air Temperature Humidity Sensors

The system can be applied to many agricultural and environmental scenarios.

1. Precision Agriculture

Farm managers can monitor root-zone moisture together with atmospheric conditions to support irrigation decisions.

2. Greenhouse Monitoring

Air temperature and humidity are critical parameters for greenhouse environmental management, while soil measurements provide information about the crop root zone.

3. Orchard Monitoring

Distributed LoRaWAN sensors can monitor environmental conditions across different areas of an orchard.

4. Agricultural Research

Researchers can collect synchronized soil and air datasets for:

Crop-growth studies
Irrigation experiments
Microclimate analysis
Soil-water relationship studies

5. Nursery and Crop Production

Temperature and moisture monitoring can help maintain more consistent growing conditions.

6. Environmental Monitoring

The same IoT architecture can be adapted for broader soil and atmospheric environmental monitoring.

ISO/IEC 30179:2023 specifically addresses IoT systems for ecological environment monitoring, including natural entities such as air and soil.

9. What Should Buyers Check Before Purchasing?

When selecting a soil and air temperature humidity monitoring system, buyers should evaluate more than the sensor itself.

Sensor Parameters

Confirm:

Soil temperature range
Soil moisture range
Air temperature range
Air humidity range
Accuracy
Resolution
Response time
Sensor protection rating

Communication

Confirm whether the project requires:

RS485
LoRa
LoRaWAN
4G
WiFi
MQTT
JSON

Power Supply

For remote agricultural sites, consider:

Solar power
Battery operation
External DC power
Low-power communication requirements

Software

Ask whether the supplier provides:

Cloud server
Web dashboard
Mobile access
Historical data
Data export
Alarm functions
API or MQTT integration

Customization

For B2B projects, customization can be particularly important.

Possible customization requirements include:

Sensor combinations
Measurement parameters
Communication protocol
LoRaWAN frequency band
Data transmission interval
Cloud platform
Housing
Cable length
Connector
OEM logo

Honde’s published materials indicate that its environmental monitoring architecture can be customized with different sensor combinations and communication solutions.

10. Soil and Air Monitoring: A More Complete Picture of Crop Conditions

A common mistake in agricultural monitoring is to focus on a single parameter.

For example:

Soil Moisture Only

can tell you whether the soil is wet or dry, but it does not explain the complete environmental condition.

Adding soil temperature gives information about the root-zone thermal environment.

Adding air temperature and humidity provides information about atmospheric conditions.

The resulting dataset becomes:

Soil Moisture + Soil Temperature + Air Temperature + Air Humidity

This four-parameter combination creates a much stronger foundation for precision irrigation and environmental analysis.
