DRAGINO LHT65S-EU868-NE117 Temperature & Humidity Sensor

Overview

The Dragino LHT65S-NE117 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 LHT65S-NE117 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.

LHT65S-NE117 external probe uses TI TMP117A NIST traceability temperature sensor, with 0.1°C accuracy in normal temperature range.

LHT65S-NE117 has a built-in 2400mAh non-chargeable battery which can be used for up to 10 years*.

LHT65S-NE117 is full compatible with LoRaWAN v1.0.3 Class A protocol, it can work with a standard LoRaWAN gateway.

LHT65S-NE117 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

The use of the external antenna improves the coverage compared to LHT65N-NE117.
