## Long description

Milesight EM300-TH-868M is an outdoor temperature and humidity sensor that communicates over LoRaWAN at 868 MHz for remote environmental monitoring. The device measures ambient temperature and relative humidity and transmits readings wirelessly to a LoRaWAN network server. Its rugged housing and compact form factor allow installation in exposed outdoor locations for continuous monitoring of microclimate conditions in applications such as weather stations, HVAC systems, greenhouses, and building automation.
Advantages
The sensor provides long-range wireless connectivity using the 868 MHz LoRaWAN band, enabling low-power, infrequent transmissions for extended battery life. Its weather-resistant enclosure protects internal electronics from outdoor conditions while allowing accurate measurement of ambient air parameters. The EM300-TH-868M supports straightforward integration with LoRaWAN networks and standard servers, facilitating centralized data collection and trend analysis. The simple mounting options and compact design make placement flexible and installation quick.
Suitable for
 Outdoor weather monitoring and microclimate observation
 Greenhouse environment control and crop monitoring
 HVAC system performance monitoring and remote site checks
 Building automation and facility environmental logging
 Data collection for remote sensors in agriculture and infrastructure
Key specifications
 Measured parameters: ambient temperature and relative humidity
 Wireless technology: LoRaWAN at 868 MHz
 Enclosure: weather-resistant outdoor housing suitable for exposed installations
 Power: low-power operation designed for long battery life (battery-powered)
 Mounting: compact form factor with options for fixed outdoor mounting

How to use
Install the sensor in a location representative of the area to be monitored, avoiding direct sunlight and locations immediately adjacent to heat sources to ensure accurate temperature readings. Mount the device at an appropriate height and secure it using the provided mounting points or recommended brackets. Register the device on a LoRaWAN network server and confirm correct device configuration and uplink settings. After power-up, the sensor will begin periodic transmissions of temperature and humidity data to the network server where readings can be stored, visualized, and used for alerts or analytics.
Usage recommendations
For reliable outdoor measurements, place the sensor in a shaded, ventilated position and perform occasional visual inspections of the housing and battery level. Configure reporting intervals and thresholds on the network server to balance power consumption with monitoring granularity. Use calibrated reference instruments to verify measurement accuracy if precise data is required for control systems or compliance.
