Dragino S31B Temperature and Humidity Sensor (LoRaWAN, NB-IoT & LTE-M)
The Dragino S31B is a temperature and humidity sensor designed for long range, low power environmental monitoring across LoRaWAN, NB-IoT, and LTE-M networks. It is suitable for both indoor and outdoor deployments where consistent measurement of ambient temperature and relative humidity is required over extended periods.
Practical Environmental Monitoring The S31B is commonly used in buildings, storage facilities, cold rooms, plant rooms, and outdoor enclosures where reliable environmental data is important for compliance, asset protection, or operational oversight.
Low Power, Long Term Operation Designed for low power operation, the S31B supports long term monitoring in locations where regular maintenance access may be limited. This makes it suitable for both fixed installations and remote monitoring applications.
Multi-Network Connectivity The S31B platform is available in LoRaWAN, NB-IoT, and LTE-M variants, allowing users to select the most appropriate network for their deployment. This supports private LoRaWAN networks as well as carrier operated cellular networks with broad coverage.
Enhanced Functionality with Telemetry2U Integration When combined with the Telemetry2U IoT platform, the S31B can be configured for real time dashboards, historical data logging, alerting, and device management. Telemetry2U provides a supported environment for monitoring trends, setting threshold based notifications, and managing devices at scale.
