Description
The Dragino LHT65S-NE117-EU868 is the LHT65N variant with an external antenna. It is a LoRaWAN-based sensor for the simultaneous acquisition of indoor climate and a second, application-specific measured variable. It combines an integrated temperature and humidity sensor with an external, high-precision temperature probe and transmits both measured values energy-efficiently via LoRaWAN to the IoT platform.
This variant uses a Texas Instruments TMP117A for the external measuring point, achieving an accuracy of ±0.1 °C, significantly better than a standard temperature probe. It is suitable for applications where small temperature differences are critical, such as calibration, validation of cold chains, pharmaceutical warehouses with GDP requirements, or laboratory climate monitoring.
The integrated datalog function ensures that no measurement data is lost even during temporary connection failures. Buffered values are automatically retransmitted once the connection is restored.
