LHT65N-NE117 – Temperature & Humidity Sensor with High Precision Probe – Dragino
 General Description
 Dragino 's LHT65N-NE117 is a long-range LoRaWAN sensor for temperature and humidity monitoring. It integrates internal T&H sensors and a high-precision, NIST-certified TMP117A external probe. This probe guarantees an accuracy of ±0.1°C over the common temperature range, making this sensor ideal for demanding environments.
 Equipped with a 2400 mAh Li-SOCI2 battery , it can operate for up to 10 years . The sensor is compatible with LoRaWAN v1.0.3 Class A and offers a datalog function to ensure data retention even outside network coverage.
