DRAGINO S31-LB-EU868 Outdoor Temperature & Humidity Sensor Node (LoRaWAN EU868, IP65)

Monitor environmental conditions in remote or outdoor locations with the DRAGINO S31-LB-EU868. This robust sensor node measures temperature and humidity using a high-accuracy SHT31 sensor, and transmits data over LoRaWAN for low-power, long-range connectivity. Designed for harsh environments, it comes in an IP65-rated enclosure and can run for up to 10 years on two AA lithium batteries, making it ideal for smart agriculture, logistics, smart buildings, and industrial monitoring.

Who is it for

The S31-LB-EU868 is built for system integrators, IoT solution providers, and IT professionals who need a reliable, easy-to-deploy sensor node for outdoor or indoor use. It is especially valuable in scenarios where mains power is unavailable or where replacing batteries frequently is not an option. With its EU868 frequency band, it connects seamlessly to standard LoRaWAN gateways and networks.
