Milesight Temperature Humidity Sensor EM320-TH-868M

The Milesight EM320-TH-868M is a robust and reliable temperature and humidity sensor designed for both indoor and outdoor environments. Built on LoRaWAN® technology, this sensor enables long-range, low-power wireless transmission, making it ideal for scenarios where remote and accurate environmental monitoring is critical.

Equipped with high-precision Sensirion sensors, it measures temperatures from -30°C to +60°C and relative humidity from 0% to 100% RH, with high accuracy and resolution. Its enclosure is IP67-rated for protection against dust and water ingress, and is made from FDA-approved food-grade PC+ABS material, making it safe for direct use in food storage, pharmaceutical facilities, and cold-chain transportation.

The EM320-TH is available in two mounting options — standard screw/wall mounting and a magnetic version — to provide flexibility for various use cases, including freezers, warehouses, greenhouses, hospitals, factories, and more.

The sensor is powered by two replaceable 2700 mAh ER14505 batteries, ensuring up to 10 years of battery life (based on 10-minute interval at 25 °C). Additional features include NFC-based configuration via mobile app, threshold alarms, 3000-record local storage, data retransmission, and compatibility with Milesight LoRaWAN® gateways and the Milesight IoT Cloud platform.
