LHT65S E3 LoRaWAN Temperature and Humidity Sensor

The Dragino LHT65S E3 is a long-range LoRaWAN sensor for professional wireless sensor network applications such as irrigation systems, smart meters, smart cities, and building automation. It has a built-in temperature and humidity sensor, as well as an external high-precision temperature sensor, and features spread-spectrum communication with high interference resistance and minimal power consumption. In contrast to the LHT65, the LHT65N uses a 1x CR17450 3V lithium battery instead of an integrated one. It also supports the data logging feature, to ensure no sensor values are lost. The LHT65S is compatible with the LoRaWAN V1.0.4 protocol and can be operated through a standard LoRaWAN gateway. The LHT65S comes with 3200 retrievable records, timestamped.
