Milesight Lorawan Environment Sensor - EM320-TH-868M Magnetic Adsorption

Milesight EM320-TH LoRaWAN Sensor EU868 with magnetic mount

The Milesight EM320-TH measures temperature and humidity in a compact IP67 enclosure. This product sheet corresponds to the magnetic version, designed for quick attachment to a metallic surface, such as a cabinet, equipment, or refrigerated enclosure.

Precise measurements

Temperature is measured from -30 to +60 °C with a resolution of 0.1 °C and a typical accuracy of ±0.2 °C between 0 and 60 °C. Humidity is measured from 0 to 100 % RH with a resolution of 0.5 % and a typical accuracy of ±2 % RH at 25 °C.

Distinct magnetic version

The magnetic version weighs 102 g and is attached by magnetic adsorption. It differs from the standard version of 93.2 g designed for wall or pole mounting.

LoRaWAN EU868

The 868M reference corresponds to the EU868 band. The EM320-TH uses LoRaWAN Class A and an internal antenna. Configuration and commissioning are performed via NFC with the Milesight ToolBox application.

Battery life and storage

Two 2,700 mAh Li-SOCl2 ER14505 batteries power the sensor. Local storage retains up to 3,000 measurement sets and allows data retransmission after a network interruption.

Cold chain

The enclosure uses food-contact compatible materials, benefits from EN 12830 certification, and is suitable for cold chain, pharmacies, buildings, greenhouses, and industrial environments.
