Dragino LHT65S E3 LORAWAN Temperature & Humidity sensor external Temperature Sensor with LoRaWAN v1.0.3 Class A protocol

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

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

LHT65S 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 battery analyzer chapter.
