Milesight EM320-TH Temperature and Humidity LoRaWAN Sensor

The EM320-TH is a simple, compact and powerful LoRaWAN temperature and humidity sensor equipped with high-precision sensors in an IP67 waterproof design, applicable for use to collect accurate temperature and humidity data 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 suitable for up to 5 years of use without battery replacement. Moreover, the EM320-TH interfaces directly to UMD Chariot Platform, a cloud based application broker providing data capture abstraction and management from other applications (Subscribers, who just want to use the data, and are not interested in how it's collected).

The EM320-TH sensor suitable for both indoor and outdoor applications such as cold chain transportation, agricultural greenhouses, office buildings, hospitals, factories and more!
