Description
The Dragino LHT65N-E31F-EU868 is a LoRaWAN-based sensor for simultaneous measurement of indoor climate and a second, application-specific measured variable. It combines an integrated temperature and humidity sensor with an external, high-precision temperature and humidity probe and efficiently transmits both measured values via LoRaWAN to the IoT platform.
This variant uses a Sensirion SHT31F sensor for the external measuring point, achieving significantly higher accuracy than the internal sensor. It is suitable for applications where the second measuring point is subject to increased requirements for measurement accuracy, such as in cleanrooms, pharmaceutical warehouses, food processing, or for the validation of climate processes.
The integrated datalog function ensures that no measurement data is lost, even during temporary connection failures. Buffered values are automatically retransmitted after the connection is restored.
