Seeed Studio LHT65N LoRaWAN Temperature & Humidity Sensor (868MHz) is a longrange wireless sensor designed for accurate monitoring of air temperature and humidity. It integrates a builtin Temperature & Humidity Sensor and provides an external sensor connector for additional probes such as soil moisture sensors, tilting sensors, or external temperature probes.

The Seeed Studio LHT65N 868MHz LoRaWAN Temperature & Humidity Sensor enables users to transmit data over extremely long ranges with ultralong spread spectrum communication. It offers high interference immunity while maintaining low power consumption. This makes it suitable for professional wireless sensor network applications such as irrigation systems, smart metering, smart cities, and building automation.

The LHT65N LoRaWAN Sensor is equipped with a builtin 2400mAh nonrechargeable battery that supports more than 10 years of operation. It is fully compatible with the LoRaWAN v1.0.2 protocol and works seamlessly with standard LoRaWAN gateways. The device also supports up to 3200 data records with timestamp, which can be retrieved for further analysis.

Note: The LHT65N Temperature & Humidity Sensor is mainly designed for indoor environment monitoring.
