Dragino LHT65N-E31F-EU868 LoRaWAN Temperatur- und Luftfeuchtigkeitssensor mit externem Sensirion SHT31F Fühler bit-kit Each phototransistor is connected toThe 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
