OVERVIEW
Every site has different temperature monitoring needs, and the LHT65N and LHT65S are built to cover most of them without swapping hardware. Both come standard with a built-in temperature and humidity sensor plus an external probe.
For general room monitoring, unplug the external probe and use the built-in sensor on its own. For fridge, freezer or cold storage monitoring, the external probe reads the temperature directly from inside the unit while the device itself sits outside. One sensor, two setups.
Both models use LoRaWAN connectivity, so you get reliable monitoring across large sites, warehouses and remote locations without dropping signal. An ultra-low power design gives up to 10 years of battery life, cutting down on maintenance and battery replacement across a fleet of devices.
The two models differ in range and probe capability. The LHT65N uses a built-in antenna. The LHT65S uses an external antenna for extended range. both sensors have a built in temperature an humidity sensor and come with an external temperature probe.
Applications include automated meter reading, industrial monitoring and control, building automation, irrigation systems, and wireless alarm and security systems.

Complete your setup with OneTemp IoT Cloud
The LHT65N/S handle the sensing. A compatible gateway and OneTemp IoT Cloud handles everything after that. Connect your sensors, visualise live temperature and humidity data on custom dashboards, set automated alerts for out-of-range readings, and manage your entire device network from one login. Pre-configured payload formatters mean less setup time, and with local support built in, you’re never troubleshooting alone.
Dragino LHT65N/S – LoRaWAN Indoor Temperature & Humidity Sensor
The LHT65N and LHT65S are indoor LoRaWAN temperature and humidity sensors with a built-in sensor and an external probe as standard. Unplug the probe for room monitoring, or use it alone for fridge and cold storage checks. Long range capability and up to 10 years battery life.
