Description

The Dragino S31B is a specialized NB-IoT Temperature and Humidity Sensor designed for seamless industrial and agricultural data acquisition. Unlike external probe models, the S31B features an integrated Sensirion SHT31 digital sensor housed directly within its professional waterproof and anti-condensation casing. This design ensures superior reliability and long-term stability by protecting the precision electronics from moisture ingress. With support for global NB-IoT cellular bands, the S31B provides an ideal solution for remote environmental tracking where LoRaWAN infrastructure is unavailable.

Professional Environmental Intelligence

Instant Threshold Alarms Continuously monitors conditions and triggers an immediate uplink alert the moment temperature or humidity levels cross user-defined limits.
Wireless Maintenance Easily configure parameters locally via Bluetooth (BLE) and perform remote firmware upgrades via OTA (Over-The-Air) for multi-year maintenance.

Smart Monitoring Use Cases

• Smart Barns & Silos: Ensure optimal climate conditions to protect livestock and prevent grain spoilage.
• Greenhouse Automation: Track precise humidity levels to manage irrigation and ventilation systems more effectively.
• Public Utilities: Monitor conditions in high-moisture outdoor areas or underground utility chambers.
