The Dragino LHT52 Indoor LoRaWAN Temperature & Humidity Sensor is a Long Range LoRaWAN Sensor. It includes a built-in Temperature & Humidity Sensor and a USB Type-C sensor connector to external sensors such as an external temperature sensor.

LHT52 senses environment temperature and humidity and sends 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, etc.

LHT52 Indoor LoRaWAN Temperature & Humidity Sensor supports 2 x AAA batteries and works for a long time, up to several years. Use can replace the batteries easily after they are finished.LHT52 is fully compatible with the LoRaWAN v1.0.3 protocol, and it can work with a standard LoRaWAN gateway.

LHT52 Indoor LoRaWAN Temperature & Humidity Sensor supports the Datalog feature to ensure users won't miss sensor data. It records sensor values for every uplink. The LoRaWAN server can retrieve these values via a downlink command.

LHT52 supports the temperature alarm feature. It can uplink alarm in a short interval while temperature exceeds preset limits.
