The Dragino LHT65N-PIR is a long-range LoRaWAN® environmental sensor that combines temperature, humidity, and passive infrared (PIR) motion detection into a single battery-powered device. Designed for smart buildings, greenhouses, warehouses, laboratories, and industrial facilities, it provides reliable environmental monitoring while detecting human activity through an external PIR sensor.
With a built-in high-accuracy temperature and humidity sensor and an external 1-meter PIR probe, the LHT65N-PIR can monitor environmental conditions while detecting occupancy or movement within a 0–3 meter range. Its low-power LoRaWAN® design enables multi-year battery life, making it ideal for installations where power is unavailable.
When integrated with Microclimates EnvOS®, the LHT65N-PIR provides real-time environmental monitoring, occupancy detection, historical trending, alerts, dashboards, and automation. Trigger lighting, HVAC, ventilation, security notifications, or greenhouse workflows based on both environmental conditions and human presence.
