LHT65N – Temperature & Humidity Sensor with External Probe Input – Dragino
General Description
Dragino 's LHT65N is a long-range LoRaWAN sensor designed to measure ambient temperature and humidity. It features integrated temperature and humidity sensors and a port for connecting an external temperature probe, extending the measurement range up to 125°C.
Thanks to its non-rechargeable 2400 mAh Li-SOCI2 battery , it can operate for up to 10 years . The sensor is compatible with the LoRaWAN v1.0.3 Class A protocol, with a datalog function to store measurements locally in the event of a network failure.
