The Dragino LHT65N-E31F is a professional LoRaWAN® Temperature & Humidity Sensor (EU868) designed for long-range environmental monitoring, cold chain applications, warehouses, greenhouses and industrial IoT installations.
The device combines an internal temperature and humidity sensor with support for an external temperature sensing probe, enabling flexible monitoring in applications where the temperature measurement point is separate from the main device enclosure.
Using LoRaWAN Class A technology, the LHT65N-E31F transmits environmental measurements over long distances while maintaining low power consumption. It can be integrated with compatible LoRaWAN gateways, network servers and IoT monitoring platforms.
Its battery-powered design supports long-term operation without external power wiring, making it suitable for distributed monitoring installations.
The sensor also supports temperature and humidity threshold alarms, enabling notifications when measured conditions exceed configured limits.
The LHT65N-E31F is a practical solution for applications requiring reliable wireless monitoring of ambient conditions and external temperature measurement.
