Milesight LoRaWAN Temperature and Humidity Sensor EM320-TH
The need for temperature and humidity monitoring never decreases. Widespread but essential, the temperature and humidity sensor serves applications across industries. Milesight introduces LoRaWAN® EM320-TH Temperature and Humidity Sensor to offer you the best price-performance ratio. Two optional versions are available – A Standard and A Magnetic Version.

  • Food-safe and IP67 Rated Enclosure.
  • Data Storage and Retransmission.
  • Magnetic/Standard Versions for Versatile Applications.
  • Optimized Accuracy and Resolution with the Best Price Competitiveness.

Robust IP67 Rated Enclosure
The EM320-TH Temperature & Humidity Sensor is equipped with IP67 rated enclosure which enables it to function properly even in the most demanding environments.

FDA-approved Food Contact Materials
With FDA-approved food contact materials, EM320-TH eliminates any potential health concerns and provides proven safety when it comes into contact with the food.

Sensitive and Accurate

  • High precision sensibility for subtle changes monitoring.
  • Sensirion SHT 41.
  • Wide Measuring Range: -30℃-60℃; 0%-100% RH (Relative Humidity).
  • High Resolution: 0.1℃; 0.5% RH.
  • Optimized Accuracy: ±0.2℃, ±2%RH.

Data Storage and Retransmission
EM320-TH has been upgraded with data storage and retransmission. EM320-TH can store up to 3000 sets of historical data records with time stamps. When the connection fails, EM320-TH will continue to collect and store environment data. Once reconnected, the data collected during that period will be retransmitted to the gateway, thus avoiding data loss. This feature is appropriate for applications that lay emphasis on information and data integrity.

Versatile Applications

  • Time Saving.
  • Cost-effective.
  • Efficient.
  • Low Maintenance.

Ultra-Low Power Consumption
Built-in 2 × 2700 mAh ER14505 Li-SOCL2 replaceable batteries ensure more than 5 years service life in low temperature environments.

LoRaWAN® Based

  • Compliant with standard LoRaWAN® gateways and network servers.
  • Data transmission range up to 15 km in rural areas and 2 km in urban areas.

Compliant with Milesight IoT Cloud
LoRaWAN® EM320-TH Sensor is compatible with Milesight IoT Cloud to monitor and control the device at your fingertips.

Effortless Configuration via NFC
Step 1. Install the Milesight ToolBox.
Step 2. Enable NFC and run ToolBox, then attach your phone to the device.
Step 3. Verify the password and start configuring.

EM320-TH Milesight LoRaWAN Temperature & Humidity Sensor - Installation


Standard, Magnetic


Smart Agriculture
Monitor temperature and humidity in the greenhouse, and collect accurate and real-time data to adjust irrigation and ventilation systems accordingly, thus maintaining the optimum environment for crops.

Smart Building
Monitor indoor temperature and humidity in buildings such as apartments, offices and schools, and connect with heating, ventilation and air conditioning systems to optimize energy usage.

Smart Factory
Monitor temperature and humidity in the harsh environments in factories or scenarios that demand precise data such as IT server room to prevent rust or fungus damage.


Smart Cold Chain
With the feature of easy installation, and the ability to store data when the network fails, EM320-TH Magnetic version is suitable for Cold Chain which requires constant monitoring and data tracking. Food-grade enclosure provides double guarantee when comes into contact with the cargo such as food, beverage and pharmaceuticals.

Smart Refrigeratory
EM320-TH greatly facilitates temperature and humidity monitoring for refrigerators since the magnetic version can easily be attached to the freezer. EM320-TH sensor helps ensure the optimal storage conditions to prevent quantitative and qualitative food losses.

Smart Pharmacy
Pharmaceutical storage requires precise environment control as well as environment monitoring. Magnetic mounting, high-precision sensor and food-grade materials make EM320-TH the perfect choice for pharmacy environment monitoring.
