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

1580 Feature: LHT65N will wait for ACK for each uplink, If LHT65N doesn't get ACK from the IoT server, it will consider the message doesn't arrive server and store it. LHT65N keeps sending messages in normal periodically. Once LHT65N gets ACK from a server, it will consider the network is ok and start to send the not-arrive message.
