Dragino LHT52 indoor LoRaWAN Temperature & Humidity Sensor

The Dragino LHT52 Temperature & Humidity sensor is a Long Range LoRaWAN Sensor. It includes a built-in Temperature & Humidity sensor and has a USB Type-C sensor connector to connect 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, and so on.

LHT52 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 LoRaWAN v1.0.3 protocol, it can work with standard LoRaWAN gateway.

LHT52 supports Datalog feature to make sure users won't miss sensor data. It records sensor values for every uplink. These values can be retrieved by LoRaWAN server via downlink command.

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

Note: batteries and external temperature sensor are not included. Please order them separately.
