DRAGINO · Sensor · LoRa · Temperature and Humidity Sensor Node Outdoor · LHT65N-E31F-EU868

The Dragino LHT65N-E31F Temperature &amp Humidity sensor is a Long Range LoRaWAN Sensor. It includes&nbspa built-in Temperature &amp Humidity sensor&nbspand has an&nbspexternal Temperature &amp Humidity probe.

The LHT65N-E31F allows users to&nbspsend 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-E31F&nbspexternal probe uses&nbspSensirion SHT31F high accurancy Temperature &amp Humidity sensor.

LHT65N-E31F&nbsphas&nbspa built-in 2400mAh non-chargeable battery&nbspwhich can be used for up to 10 years*.

LHT65N-E31F&nbspis full compatible with&nbspLoRaWAN v1.0.3 Class A protocol, it can work with a standard LoRaWAN gateway.

LHT65N-E31F&nbspsupports&nbspDatalog 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.

*The actual battery life depends on how often to send data.
