SenseCore Temp & Humidity Sensor

The SenseCore Temp & Humidity Sensor, based on the Dragino S31x-LB/LS model, is a LoRaWAN solution designed to measure the surrounding environment’s temperature and relative air humidity precisely, and then upload this data to an IoT server via the LoRaWAN wireless protocol.

Key Features

  • Accurate Measurement: Utilizes the SHT31 sensor from Sensirion, known for its high reliability and long-term stability. The sensor is housed in a waterproof, anti-condensation casing.
  • LoRaWAN Technology: Ensures ultra-long range communication with high interference immunity while minimizing power consumption.
  • Temperature & Humidity Alarm: Allows users to set alarms for instant notifications based on temperature changes.
  • Datalog Feature: Stores data locally when the LoRaWAN network is unavailable, and uploads it once the network is restored.
  • Easy Configuration: Supports BLE configuration and wireless OTA updates.
  • Long-Term Use: Powered by an 8500mAh Li-SOCI2 battery or a solar panel with a 3000mAh Li-on battery, designed for up to 5 years of use.
  • Pre-loaded Unique Keys: Each device comes with unique keys for seamless LoRaWAN registration and automatic connection upon powering on.
