he Dragino LHT65N/S-DS Door Sensor is a Long Range LoRaWAN Sensor. It includes a built-in Temperature & Humidity sensor and a metal Door Sensor.

The LHT65N/S-DS allows users to send data and reach extremely long ranges. It provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current consumption. It targets professional wireless sensor network applications such as irrigation systems, smart metering, smart cities, building automation, and so on.

LHT65N/S-DS has a built-in 2400mAh non-chargeable battery which can be used for up to 10 years*.

LHT65N/S-DS is full compatible with LoRaWAN v1.0.3 Class A protocol, it can work with a standard LoRaWAN gateway.

*The actual battery life depends on how often to send data, please see battery analyzer chapter.

Default FW in AS923, but it support US915, AU915 and all 900MHz Frequency by loading different FW, it could also support 868MHz if loading 868MHz FW, but there will be slight 0.5-1dB loss here. Customer could check with us if they need AU915 FW, we could reprogram it for customer
