The Dragino LHT65N-E31F Temperature & Humidity sensor is a Long Range LoRaWAN Sensor. It includes a built-in Temperature & Humidity sensor and has an external Temperature & Humidity probe.

The LHT65N-E31F allows users to send data and reach extremely long ranges. It provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current consumption. It targets professional wireless sensor network applications such as irrigation systems, smart metering, smart cities, building automation, and so on.

LHT65N-E31F external probe uses Sensirion SHT31F high accurancy Temperature & Humidity sensor.

LHT65N-E31F has a built-in 2400mAh non-chargeable battery which can be used for up to 10 years*.

LHT65N-E31F is full compatible with LoRaWAN v1.0.3 Class A protocol, it can work with a standard LoRaWAN gateway.

LHT65N-E31F supports Datalog feature. It will record the data when there is no network coverage and users can retrieve the sensor value later to ensure no miss for every sensor reading.
