33 The Dragino LTC2 Industrial LoRaWAN Temperature Transmitter is designed to monitor temperature for different environment. It supports to read (% style="color:#4472c4" %)**PT100 probe**(%%) and convert the value to temperature and uplink to IoT server via LoRaWAN protocol.
34
35
36 LTC2 supports (% style="color:#4472c4" %)**Datalog feature**(%%). User can retrieve the sensor value via LoRaWAN downlink command.
37
38
39 LTC2 is powered by (% style="color:#4472c4" %)**8500mA Li-SOCI2 battery**(%%) for long time measurement. The battery can run 2~~10 years depends on the network environment and working mode.
40
41
42 Each LTC2 has (% style="color:#4472c4" %)**two internal 24-bit ADC interfaces** (%%)and are calibrated on 12 set resistors to make sure the accuracy measurement on wide range.
43
44
45 LTC2 is LoRaWAN v1.0.3 compatible. Each LTC2 is pre-load with a set of unique keys for LoRaWAN registration, register these keys to local LoRaWAN server and it will auto connect after power on.

189
190 LTC2 has different probe option provided for ordering, if user has LTC2 with probe, just skip this step. If user want to connect to a 3^^rd^^ party PT100 probe, please see [[CONNECT A 3(% class="wikiinternallink wikiinternallink wikiinternallink wikiinternallink wikiinternallink wikiinternallink" %)^^rd^^ PARTY PT100 probe>>path:#Customized_PT100]](%%).
191
192
193 === 2.2  How it works? ===
194
195 (((
196 The LTC2 is working in LoRaWAN OTAA Class A mode. Each LTC2 is shipped with a worldwide unique set of OTAA and ABP keys. User needs to input the OTAA or ABP keys in the LoRaWAN network server so to register. LTC2 will join the LoRaWAN network and start to transmit data. The default period for each uplink is **20 minutes**.
197
198 On each uplink, LTC2 will check its two ADC Interfaces and get the temperature from the sensor and send out to server.

276
277
278
279 After power on, LTC2 will auto join to TTN network via the LoRaWAN coverage by DLOS8. After join success, LTC2 will start to update message to IoT server.
