Dragino LHT65N-DC -- LoRaWAN Dry Contact Sensor EU868

The Dragino LHT65N-DC is a LoRaWAN Dry Contact Sensor is a Long Range LoRaWAN Sensor. It detects dry contact status, open/ close status, counts, and then upload to IoT server via LoRaWAN network. It includes a built-in Temperature & Humidity sensor and 3-wire(VCC/ GND/INT) for dry contact.

LHT65N-DC supports open alarm feature, user can set open alarm for instant notice. The sensor supports Datalog feature, it can save the data when there is no network and uplink when network recover.

LHT65N-DC supports Datalog feature. It will record the data when there is no network coverage and users can retrieve the sensor value later to ensure no miss for every sensor reading.

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

LHT65N-DC 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.
