Dragino S31-LB LoRaWAN Temperature & Humidity Sensor – Battery Powered (EU868)

The Dragino S31-LB is a battery-powered LoRaWAN temperature and humidity sensor designed for accurate environmental monitoring in industrial facilities, warehouses, agricultural installations, smart buildings and remote IoT applications.

The device measures ambient temperature and relative humidity, transmitting data wirelessly through a compatible LoRaWAN gateway to an IoT platform or network server.

Operating on the EU868 frequency band, the S31-LB uses low-power LoRaWAN communication to support long-range data transmission with minimal energy consumption.

Powered by a 3.6 V lithium thionyl chloride (Li-SOCl₂) battery, the sensor is designed for long-term deployment without external power connections. Battery life depends on reporting frequency, network conditions and operating temperature.

Its compact, weather-resistant design and IP67-rated enclosure, as specified in the existing product listing, make the S31-LB suitable for demanding indoor and outdoor environmental monitoring applications.

The sensor supports LoRaWAN Class A operation, enabling efficient communication with compatible gateways and network servers.

The Dragino S31-LB is a practical solution for businesses and system integrators seeking reliable, low-maintenance temperature and humidity monitoring across distributed locations.
