MILESIGHT - LoRaWan temperature and humidity sensor + radiation shield

EM320-TH Temperature and Humidity Sensor

Precise, versatile monitoring

Milesight's EM320-TH sensor is a device based on LoRaWAN® technology, designed to accurately monitor temperature and humidity in a variety of environments such as cold chains, smart buildings and connected agriculture. It combines an aesthetic, practical design with great robustness thanks to its IP67-certified housing, capable of operating in extreme conditions.

The sensor uses FDA-compliant materials for safe contact with food, making the device ideal for monitoring food warehouses, pharmacies or cold rooms. It is EN12830 certified, ensuring traceability and data reliability in professional environments. The data storage and retransmission function prevents any loss of information, even in the event of a network failure.

With its two versions - magnetic and standard - the EM320-TH is quick and easy to install in a wide range of applications, including refrigerated equipment, greenhouses, buildings and factories. Its low energy consumption gives it an autonomy of over 10 years, even in cold environments.
