LHT65S E3 LoRaWAN Temperature and Humidity Sensor

The Dragino LHT65S E3 measures temperature and humidity with the built-in sensor and additionally the temperature with the external E3 probe, which is connected to the USB-C socket. It sends the values via LoRaWAN. It is powered by a replaceable CR17450 battery, which is included.

Each LHT65S comes with its own keys for OTAA activation, so it can be registered for example in The Things Network. Up to 3328 readings are stored with a time stamp and can be retrieved via downlink.
