Overview
EM300-TH overview
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.
