LHT65N/S-DC LoRaWAN Dry Contact Sensor
The Dragino LHT65N/S-DC is a LoRaWAN Dry Contact Sensor is a Long Range LoRaWAN Sensor. It detects dry contact status, open/ close status, counts, and then uploads to the IoT server via the LoRaWAN network. It includes a built-in Temperature & Humidity sensor and 3-wire(VCC/ GND/INT) for dry contact.
LHT65N/S-DC supports an open alarm feature, user can set the open alarm for instant notice. The sensor supports the Datalog feature, it can save the data when there is no network and uplink when the network recovers.
LHT65N/S-DC supports the 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/S-DC has a built-in 2400mAh non-chargeable battery which can be used for up to 10 years*.
LHT65N/S-DC is fully 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 the battery analyzer chapter.
