EM320-TH is a simple, compact and powerful LoRaWAN temperature & humidity sensor. It is equipped with high-precision sensors and IP67 waterproof design, applicable for accurate temperature and humidity data detection in various harsh environments. Food-grade material’s enclosure and magnet design allow it to be placed in freezers and refrigerators and in contact with food or medicines safely.
In addition to LoRaWAN technology with low power consumption, it has built-in high-capacity batteries available for usage for up to 5 years without battery replacement. Moreover, EM320-TH LoRaWAN Temperature Humidity Sensor is compatible with both Milesight LoRaWAN Gateway and Milesight IoT Cloud to achieve remote data monitoring and management. It is suitable for both indoor and outdoor applications such as cold chain transportation, agricultural
greenhouses, office buildings, hospitals, factories, etc.
Esthetic and Practical Design
Robust IP67 Rated Enclosure
EM320-TH is equipped with IP67 rated enclosure which enables it to function properly even in the most demanding environments.
Sensitive and Accurate
- 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.
