DRAGINO NB-IoT LTE-M Outdoor Temperature Humidity Sensor
DRAGINO NB-IoT LTE-M Outdoor Temperature Humidity Sensor is an outdoor temperature and humidity monitoring sensor designed for IoT applications. It uses a Sensirion SHT31 digital sensor to measure temperature and relative humidity, then transmits readings to an IoT server over cellular networks. The S31-NB/S31B-NB supports NB-IoT, while the S31-CB/S31B-CB supports NB-IoT and LTE-M connectivity. Both versions feature an 8500mAh Li-SOCI2 battery, IP66 enclosure and support remote configuration via BLE.
The DRAGINO NB-IoT LTE-M Outdoor Temperature Humidity Sensor are cellular IoT temperature and humidity sensors designed for remote environmental monitoring. They measure surrounding temperature and relative humidity and transmit the collected data to an IoT server.
Both versions use the Sensirion SHT31 digital temperature and humidity sensor. Dragino states that the SHT31 is fully calibrated, linearised and temperature compensated, with the sensing element installed in a waterproof anti-condensation casing.
The S31-NB/S31B-NB uses NB-IoT connectivity, while the S31-CB/S31B-CB supports NB-IoT and LTE-M/CAT-M1 connectivity. Both models support several communication methods for transferring data to IoT platforms.
How it works
- The SHT31 sensor measures the surrounding temperature and relative humidity.
- The sensor can perform multiple measurements before sending an uplink.
- Measurements are transmitted periodically to an IoT server through the supported cellular network.
- Data communication can use protocols such as MQTT, MQTTs, TCP and UDP. The S31-CB/S31B-CB additionally supports CoAP.
- BLE connectivity allows remote configuration and firmware updates.
- Temperature and humidity alarm functions are supported for applications requiring condition monitoring.
Why choose this product
- Provides remote monitoring without requiring a wired sensor connection to the monitoring system.
- Uses the Sensirion SHT31 sensing element for temperature and humidity measurement.
- The IP66 enclosure is suited to outdoor environmental monitoring applications.
- The 8500/19000mAh Li-SOCI2 battery is designed for long-term operation.
- The S31-CB/S31B-CB provides additional LTE-M/CAT-M1 connectivity alongside NB-IoT.
- Optional built-in SIM and pre-configured IoT server versions are available according to the manufacturer's order information.
Benefits
The S31 series can help reduce the need for manual environmental measurements by automatically sending recorded conditions to an IoT platform. Its cellular connectivity and battery-powered design make it suitable for installations where continuous wired communications are not practical.
