Milesight EM300 Waterproof Temperature & Humidity Sensor

Milesight's EM300-TH-868M is a robust, waterproof, temperature and humidity sensor. EM300-TH is designed to monitor conditions in cold-chain, food storage, greenhouses and warehouses. IP67-rated, it's water and dust proof, and the enclosure is UV-resistant - making it suited to use in industry.

The unit is configurable via an NFC application to select different operational modes, including periodic sampling and threshold-based transmissions. The sensor measurement interval can be set for different periods, and in threshold mode upper and lower bounds can be set.

The unit is powered from one or two A-sized batteries. One A-cell is included and gives the unit a battery life of around five years. The sensor can be fitted with an additional battery for up to 10 years of battery life.

The sensors can be configured via NFC using Milesight's Android app. Milesight's Toolbox software for Windows also provides configuration and firmware updates using the sensor's internal USB-C connector.
