The LHT65N is a dedicated environmental sensor node that leverages the LoRaWAN protocol for long-range, low-power wireless communication. It integrates a precision sensor for ambient air temperature and humidity, making it ideal for remote monitoring where power infrastructure is unavailable. The device’s core functionality is built around energy efficiency, enabling multi-year operation from its non-rechargeable lithium battery.
Beyond standard air sensing, the module supports an external DS18B20 temperature probe (sold separately), allowing for surface or liquid temperature measurement via a 2-meter cable. It offers advanced features like historical data retrieval via downlink commands and configurable alarm thresholds, which can be set using AT commands for flexible deployment in various IoT and industrial monitoring scenarios.
