Dragino LHT65S LoRaWAN temperature and humidity sensor

The Dragino LHT65S temperature and humidity sensor is a long-range LoRaWAN sensor. It contains a built-in temperature and humidity sensor and has a connector for connecting an external temperature sensor.

The LHT65S allows users to send data over extremely long distances. It provides ultra wide range spread spectrum communication and high immunity to interference while minimizing current consumption. It is designed for professional wireless sensor networks such as irrigation systems, smart metering, smart cities, building automation, etc.

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

LHT65S is fully compliant with LoRaWAN v1.0.3 class A protocol, it can work with standard LoRaWAN gateway.

LHT65S supports Datalog function. It will record data when there is no network coverage and users can retrieve sensor values ​​later to ensure that no sensor reading is missed.

*Actual battery life depends on data transmission frequency, see battery analyzer section.
