LoRaWAN® · Temperature, Humidity, External Probe

Dragino LHT65NKnow the moment it drifts.

The Dragino LHT65N is a battery-powered LoRaWAN temperature and humidity sensor with a 2m external temperature probe. The built-in sensor measures -40 to 80°C and 0 to 96 %RH, while the probe reaches -55 to 125°C - ideal for fridges, freezers, server rooms, greenhouses and damp and mould monitoring. Readings are stored on the device when out of coverage, and the replaceable 2400mAh battery is rated for up to 10 years.
