    Description

    EM300-TH Description

    Core Purpose

    The EM300-TH is designed to monitor temperature and humidity in indoor and outdoor environments. It continuously measures environmental conditions and sends the data wirelessly to a central system for remote visibility. This allows teams to track climate conditions without manual checks.

    Connectivity and Communication

    The device uses LoRaWAN for long-range, low-power communication, making it suitable for wide-area deployments. Data can be transmitted over long distances while maintaining low energy use, helping the sensor operate for years on a single battery. NFC support allows quick setup and configuration during installation.

    Monitoring Capabilities

    The sensor measures both temperature and humidity with consistent reporting intervals. It can store historical data locally and resend it if a transmission is missed, helping prevent data gaps. Threshold alarms allow users to be notified when conditions move outside acceptable ranges.

    Power and Environmental Suitability

    A built-in 4000 mAh battery supports multi-year operation without frequent maintenance. The IP67-rated enclosure protects the device from dust, water, and harsh outdoor conditions. This makes it suitable for use in demanding environments such as industrial sites or outdoor installations.

    Industry Applications

    EM300-TH Industrial Applications

    Industrial Facilities

    The sensor helps monitor temperature and humidity in factories and production areas where stable environmental conditions matter. Remote reporting reduces the need for manual inspections.

    Healthcare and Laboratories

    Hospitals and labs can use the device to track indoor climate conditions that support equipment reliability and occupant comfort. Alerts help staff respond quickly to abnormal changes.

    Agriculture and Greenhouses

    In greenhouses and agricultural buildings, the sensor supports climate awareness for crops and storage areas. Long battery life enables continuous monitoring with minimal upkeep.

    Commercial Buildings

    Offices and public buildings can use the sensor to understand indoor environmental trends over time. This supports better facility management without complex infrastructure.
