DRAGINO Cellular Temperature Humidity IoT Sensor with E-Ink Display
DRAGINO Cellular Temperature Humidity IoT Sensor with E-Ink Display is a wireless temperature and humidity sensor designed for IoT monitoring applications using NB-IoT and LTE-M cellular networks. It measures ambient temperature and relative humidity, displays readings on a 2.7-inch E-Ink display and sends data to an IoT server. The sensor features configurable measurement and alarm functions, Bluetooth configuration, wireless OTA firmware updates and an 8000mAh Li-SOCl2 battery for long-term operation.
The DRAGINO Cellular Temperature Humidity IoT Sensor with E-Ink Display is a cellular IoT temperature and humidity sensor for monitoring environmental conditions and transmitting measurements to an IoT server through NB-IoT or LTE-M networks. The device uses a Sensirion digital temperature and humidity sensing element and provides local readings through its 2.7-inch E-Ink display.
The sensor supports configurable uplink intervals and multiple sampling through a single uplink, making it suitable for applications where environmental measurements need to be collected remotely. Temperature and humidity alarm thresholds can also be configured so that changes outside the required limits can be identified.
Configuration can be performed through Bluetooth, while wireless OTA firmware updates simplify ongoing device maintenance. The S31B-FE uses an 8000mAh Li-SOCl2 non-rechargeable battery, with Dragino stating battery life can reach up to five years depending on the uplink interval.
How it works
- The integrated sensor measures ambient temperature and relative humidity.
- Measurement data is processed by the S31B-FE and can be sampled according to the configured operating parameters.
- Data is transmitted to an IoT server using NB-IoT or LTE-M cellular connectivity.
- The 2.7-inch E-Ink display provides a local indication of environmental readings.
- Configurable temperature and humidity alarms allow threshold conditions to be monitored remotely.
