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 features a built-in temperature and humidity sensor, as well as an external high-precision temperature sensor, offering spread spectrum communication with high interference resistance and minimal power consumption. Compared to the LHT65, the LHT65N uses a 1x CR17450 3V lithium battery instead of an integrated battery. Additionally, it supports the data-logging function to ensure that no sensor values are lost. The LHT65S is compatible with the LoRaWAN V1.0.4 protocol and can be operated via a standard LoRaWAN gateway. The LHT65S has 3200 retrievable data records stored with timestamps.
