LHT65 – Temperature & Humidity Sensor with External Probe Input – Dragino
 General Description
 Dragino 's LHT65 is a long-range LoRaWAN sensor for monitoring temperature and humidity. It integrates a reliable and accurate Sensirion SHT20 sensor, as well as an external port for connecting additional sensors (temperature, soil moisture, inclinometer, etc.).
 Thanks to its 2400 mAh Li-SOCI2 battery , non-rechargeable, it can operate for up to 10 years . Compliant with the LoRaWAN v1.0.4 Class A protocol, it is suitable for industrial, agricultural and urban environments. It records up to 3200 sets of time-stamped data that can be viewed remotely.
