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
39 *Battery life depends how often to send data, please see [[battery analyzer>>||anchor="H4.2A0PowerConsumptionAnalyze"]].

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**.

189 Assume the DLOS8 is already set to connect to [[TTN V3 network >>url:https://eu1.cloud.thethings.network/]]. We need to add the LHT52 device in TTN V3 portal. 
190
191
192 (% style="color:blue" %)**Step 1**(%%):  Create a device in TTN V3 with the OTAA keys from LHT52.

477 * Each data entry is 11 bytes, to save airtime and battery, LHT52 will send max bytes according to the current DR and Frequency bands.
478
479 For example, in US915 band, the max payload for different DR is:
480
481 1. DR0: max is 11 bytes so one entry of data
482 1. DR1: max is 53 bytes so devices will upload 4 entries of data (total 44 bytes)
483 1. DR2: total payload includes 11 entries of data
484 1. DR3: total payload includes 22 entries of data.
485
486
487 **Notice**: LHT52 will save 178 set of history data, If device doesn’t have any data in the polling time. Device will uplink 11 bytes of 0.
