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.
