LHT52 - LoRaWAN Indoor Temperature & Humidity Sensor

Dragino LHT52 Is a LoRaWAN temperature & humidity sensor. The sensor is built-in and it has a USB-C connector to connect an optional external temperature sensor.

LHT52 senses environment temperature and humidity and sends these values via long-range wireless LoRaWAN protocol. It uses 2 x AAA batteries (not included) and works for a long time (up to several years). You can replace the batteries easily.

LHT52 is fully compatible with LoRaWAN v1.0.3 protocol and it will work with standard LoRaWAN gateways. It records sensor values for every uplink (default: 20 minutes), but LHT52 also supports datalogging to make sure you won't miss sensor data. These values can be retrieved by LoRaWAN server via downlink command.

LHT52 supports temperature alarm feature. It will check the built-in sensor temperature in a short interval. If the temperature exceeds the pre-configure range, it will send an uplink immediately.
