Milesight EM300-TH LoRaWAN® Temperature & Humidity Sensor

Reliable Environmental Monitoring

The EM300-TH continuously measures temperature and relative humidity and transmits this data wirelessly via LoRaWAN®. This provides real-time insight into environmental conditions without the need for cabling or complex infrastructure.

By detecting deviations at an early stage, processes can be monitored more effectively, products can be protected, and environmental conditions can be optimally controlled.

Key Benefits

• Wireless communication via LoRaWAN®
• Accurate measurement of temperature and relative humidity
• Compact and energy-efficient design
• IP67-rated waterproof and dustproof enclosure
• Battery life of more than 5 years
• NFC configuration via smartphone
• Local data storage
• Configurable alarm notifications when thresholds are exceeded
• Easy installation without wiring
• Compatible with standard LoRaWAN® gateways and network servers

Applications

The EM300-TH is suitable for a wide range of applications, including:

• Building management and smart buildings
• Cleanrooms and controlled environments
• Warehouses and storage facilities
• Pharmaceutical storage
• Food industry applications
• Greenhouses and agriculture
• Server rooms and technical installations
• Transportation and logistics
• Museums and archives
• Environmental monitoring in production facilities

Alarm Functions and Data Logging

The sensor supports configurable alarm thresholds for both temperature and humidity. When a predefined limit is exceeded, an alert can be sent immediately via the LoRaWAN® network.

In addition, the EM300-TH features onboard data logging, allowing measurement data to be stored locally whenever network connectivity is temporarily unavailable. Once the connection is restored, the stored data can be transmitted automatically.

Compact and Robust Design

The EM300-TH is designed for long-term deployment in demanding environments. Thanks to its IP67-rated enclosure, the sensor is protected against dust, moisture, and harsh weather conditions.

Its compact dimensions allow for easy installation on walls, storage racks, technical equipment, and other monitoring locations.

LoRaWAN® Connectivity

The Milesight EM300-TH utilizes LoRaWAN® technology to provide long-range, low-power wireless communication.

Measurement data can be transmitted to a LoRaWAN® gateway, cloud platform, or building management system for monitoring, reporting, trend analysis, and alarm management.

Depending on the environment, communication ranges can reach:

• Up to 2 km in urban areas
• Up to 15 km in open environments

Ideal for Wireless Environmental Monitoring

For organizations that require continuous temperature and humidity monitoring without extensive wiring, the EM300-TH offers a reliable and scalable solution. Combined with LoRaWAN® gateways and monitoring software, it provides a complete system for environmental monitoring, historical trend analysis, and automated alarm notifications.

Why Choose the Milesight EM300-TH?

The EM300-TH combines accurate environmental measurements, long battery life, and reliable LoRaWAN® communication in a compact and rugged enclosure. This makes the sensor suitable for both standard monitoring applications and critical environments where temperature and humidity control are essential.
