Dragino LHT65N User Manual

User Manual for LoRaWAN End Nodes - LHT65N LoRaWAN Temperature & Humidity Sensor Manual
1. Introduction
1.1 What is LHT65N Temperature & Humidity Sensor
The Dragino LHT65N Temperature & Humidity sensor is a Long Range LoRaWAN Sensor. It includes abuilt-in
Temperature & Humidity sensor and has an external sensor connector to connect to an external Temperature
Sensor.
The LHT65N 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 has a built-in 2400mAh non-chargeable battery which can be used for up to 10 years*.
LHT65N is full compatible with LoRaWAN v1.0.3 Class A protocol, it can work with a standard LoRaWAN gateway.
LHT65N 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.
*The actual battery life depends on how often to send data, please see the battery analyzer chapter.
