27 The Dragino LHT52 Temperature & Humidity sensor is a Long Range LoRaWAN Sensor. It includes a (% style="color:blue" %)**built-in Temperature & Humidity sensor** (%%)and has a USB Type-C sensor connector to connect to external sensors such as external Temperature Sensor.
28
29 LHT52 (% style="color:blue" %)**senses environment temperature and humidity**(%%) and send these values via long-range wireless LoRaWAN protocol. It targets professional wireless sensor network applications such as food service, smart metering, smart cities, building automation, and so on.
30
31 LHT52 supports(% style="color:blue" %)** 2 x AAA batteries **(%%)and works for a long time up to several years. Use can replace the batteries easily after they are finished.
32
33 LHT52 is fully compatible with LoRaWAN v1.0.3 protocol, it can work with standard LoRaWAN gateway.
34
35 LHT52 supports(% style="color:blue" %)** Datalog feature** (%%)to make sure users won’t miss sensor data. It records sensor value for every uplink. These values can be retrieved by LoRaWAN server via downlink command.
36
37 LHT52 supports(% style="color:blue" %)** temperature alarm feature**(%%). It can uplink alarm in a short interval while temperature exceeds preset limits.
38

147 Each LHT52 is shipped with a worldwide unique set of LoRaWAN OTAA keys. To use LHT52 in a LoRaWAN network, user needs to input the OTAA keys in LoRaWAN network server. After this, if LHT52 is under this LoRaWAN network coverage, LHT52 can join the LoRaWAN network and start to transmit sensor data. The default period for each uplink is** 20 minutes**.

598 Datalog Feature is to ensure IoT Server can get all sampling data from Sensor even if the LoRaWAN network is down. For each sampling, LHT65N will store the reading for future retrieving purposes. There are two ways for IoT servers to get datalog from LHT65N.
