Milesight EM320-TH + SS11 is a kit for outdoor temperature and humidity monitoring, consisting of a precision sensor EM320-TH LoRaWAN EU868 and an SS11 radiation shield. The shield reduces the impact of direct solar radiation and precipitation on measurements while allowing natural air circulation around the sensor.
The EM320-TH measures temperature within a range of −30…+60°C with a typical accuracy of up to ±0,2°C and humidity 0–100% RH with a typical accuracy of ±2% RH. The device features an IP67 protection rating, storage for 3000 records, data retransmission, threshold alarms, NFC configuration, and power from two Li-SOCl₂ batteries providing more than 10 years of operation under conditions specified by the manufacturer.

EM320-TH + SS11 — Precision LoRaWAN Sensor with a Shield for Outdoor Measurements
Milesight EM320-TH + SS11 is a complete kit designed for monitoring air temperature and relative humidity in outdoor environments.
The kit combines the precision EM320-TH sensor using a Sensirion SHT41 sensing element with the SS11 shield, which reduces the impact of direct solar radiation, precipitation, and other factors that could distort air temperature measurements.
Data is transmitted wirelessly via LoRaWAN, allowing the kit to operate in distributed environmental monitoring systems without wired communication infrastructure.
Accurate Outdoor Measurement and Wireless Data Transmission
SS11 Shield
Protects the sensor from direct sunlight and precipitation, enabling a more representative air temperature measurement.
±0,2°C
The precision Sensirion SHT41 sensor enables even small changes in temperature and humidity to be recorded.
LoRaWAN EU868
Data can be transmitted over long distances to a LoRaWAN gateway and central monitoring system.
Outdoor Environmental Condition Monitoring
More Reliable Outdoor Air Temperature Measurement
Placing an unshielded temperature sensor in direct sunlight can heat its enclosure and cause readings to be higher than the actual temperature of the surrounding air.
The SS11 shield isolates the EM320-TH from direct solar radiation and partially protects it from rain, snow, and contamination while maintaining airflow around the sensor.
Sun Protection
The design reduces direct heating of the sensor by solar radiation.
Natural Ventilation
The open shield design allows free air circulation around the sensor.
Outdoor Application
The kit is particularly useful in installations requiring continuous measurement of weather conditions.
Range from −30 to +60°C
Full Range 0–100% RH
Long-Range Wireless Monitoring
The EM320-TH uses the energy-efficient LoRaWAN standard, enabling data transmission to a gateway without wired network infrastructure.
The manufacturer specifies a transmission range of up to approximately 15 km in open terrain under suitable radio conditions.
3000 Records and Automatic Retransmission
3000 records
The sensor locally stores up to 3000 sets of historical data with timestamps.
Retransmission
Data collected during temporary loss of connectivity can be transmitted after the connection is restored.
Data Retrieval
The data retrieval function provides access to stored measurement history.
Automatic Detection of Temperature and Humidity Threshold Exceedances
The EM320-TH allows alarm thresholds to be configured for temperature and humidity.
When a specified value is exceeded, the information can be transmitted via LoRaWAN and used by the supervisory system to generate an alarm or trigger automation.
More Than 10 Years of Battery Life
The sensor uses two replaceable ER14505 Li-SOCl₂ lithium batteries with a capacity of 2700 mAh each.
According to the current Milesight specification, battery life can exceed 10 years with a 10-minute reporting interval, a temperature of 25°C, and suitable LoRaWAN transmission parameters.
Quick Commissioning with Milesight ToolBox
Device parameters can be configured wirelessly using an NFC-enabled smartphone and the Milesight ToolBox app.
NFC can be used, among other things, to activate the device, configure LoRaWAN parameters, and set reporting behaviour and alarm thresholds.
IP67 and an Enclosure Designed for Demanding Conditions
IP67
The multi-layer design and sealing protect the electronics against water and dust.
Food-grade
The EM320-TH enclosure is made of material approved by the FDA for food contact.
EN12830
The sensor has EN12830 certification, which is relevant for applications including cold-chain monitoring.
Key Parameters of EM320-TH + SS11
* Manufacturer declaration for specified laboratory operating conditions, including a 10-minute reporting interval, a temperature of 25°C, and suitable LoRaWAN transmission parameters.
EM320-TH + SS11 in an Environmental Monitoring System
Temperature and humidity can be automatically transmitted from an outdoor location to a central platform.
