Overview
EM320-TH overview
Overview
The EM320-TH is a LoRaWAN temperature and humidity sensor built for cold chain, food storage and other applications that need accurate, long-life environmental monitoring. Its food-grade IP67 enclosure and EN12830 certification support compliance-focused deployments.
Connectivity
LoRaWAN backhaul sends readings to gateways and cloud platforms with low power draw. NFC configuration through the mobile app simplifies field setup without opening the enclosure.
Monitoring
High-accuracy temperature and humidity measurements feed threshold alarms, local data storage and retransmission so gaps are avoided after brief outages.
Power & Durability
Two replaceable ER14505 batteries deliver at least 10 years of life at a 10-minute reporting interval. The compact IP67 housing suits refrigerators, greenhouses, pharmacies and industrial sites.

Applications
EM320-TH applications
Cold Chain and Food Storage
The EN12830 certification and food-grade enclosure make the EM320-TH suitable for refrigerated storage, freezers, and food transport. Accurate temperature and humidity monitoring helps maintain compliance and protect product quality.
Pharmaceutical and Healthcare Facilities
Hospitals, pharmacies, and laboratories require strict environmental control. The sensor provides reliable monitoring with threshold alarms and long battery life, supporting uninterrupted supervision of medical storage areas.
Agriculture and Greenhouses
In greenhouses and agricultural environments, precise humidity and temperature control directly affects crop health. The sensor’s wide operating range and IP67 protection allow stable operation in humid and variable outdoor conditions.
Commercial Buildings and Offices
For offices and public buildings, environmental monitoring supports occupant comfort and facility management. Long-range LoRaWAN® communication allows centralised monitoring across multiple rooms or floors.
Industrial and Factory Environments
Factories and industrial sites often experience fluctuating environmental conditions. The durable enclosure, long battery life, and data retransmission capability ensure continuous monitoring even in demanding operational settings.
