Product description: IP67 LoRaWAN temperature and humidity sensor - Milesight EM320-TH-868M
The Milesight EM320-TH is a compact sensor utilizing the precise Sensirion SHT41 chip to measure temperature and humidity . It communicates wirelessly in the European LoRaWAN 868 MHz band, enabling remote data collection without running communication cables. Local storage of 3,000 measurements and retransmission reduces the risk of data loss during a temporary network outage. This standard version, without a magnet , is designed for wall or pole mounting . Parameters, alarm thresholds, and reporting frequency can be configured using the Milesight ToolBox app via NFC . Powered by two replaceable Li-SOCl2 batteries, the device achieves long operating times without frequent maintenance.
IP67 LoRaWAN temperature and humidity sensor - Milesight EM320-TH-868M.
The IP67 housing allows operation in demanding conditions.
Milesight sensor main features

LoRaWAN 868 MHz connectivity and reliable data transmission
LoRaWAN technology enables the transmission of small data packets over long distances with very low power consumption . The EM320-TH operates in the European EU868 band and supports OTAA and ABP activation modes, as well as Class A devices. Under favorable conditions, the transmission range can be up to 2 km in urban areas and up to 15 km in open areas . The sensor can be used with standard LoRaWAN gateways and network servers. If the connection is interrupted, the device continues to take measurements and store them in memory. Upon reconnection to the network , the stored data can be retransmitted , helping to maintain continuous documentation of environmental conditions.
Food-safe housing and IP67 protection
The sensor's housing is made of food-grade PC and ABS materials, approved by the FDA for contact with food and drugs . This allows the device to be used in storage areas for food, beverages, vaccines, and pharmaceuticals. The EN12830 certification further supports the sensor's use in cold chain monitoring systems. The IP67 rating protects the sensor from dust and moisture ingress, allowing it to be used in demanding environments.
The EM320-TH-868M model is suitable for wall mounting.
