The Milesight EM300-TH is a sealed LoRaWAN temperature and humidity sensor for warehouses, greenhouses, plant rooms, farm sheds and outdoor points. The IP67, UV-resistant housing takes rain and wash-down.
Why pick it
- -30 to +70 °C with ±0.3 °C from 0 to 70 °C, and 0 to 100% RH.
- Replaceable 4000 mAh cell, with room for a second: Milesight quotes up to 10 years at a 10-minute interval.
- Stores readings locally and resends after a network gap. Milesight D2D can trigger another Milesight device with no gateway.
For tighter accuracy, a food-safe housing or a magnetic mount, see the EM320-TH.
Works with any standard LoRaWAN gateway and network server, such as the Milesight UG65 indoors or the UG67 outdoors, with alerts and dashboards on IoT Factory.
