DRAGINO LHT52-EU868 Temperature & Humidity Sensor

overview

The Dragino LHT52 temperature & humidity sensor is a long range LoRaWAN sensor. It has a built-in temperature & humidity sensor as well as a USB Type-C sensor port to connect external sensors such as an external temperature sensor.

The LHT52 monitors the ambient temperature and humidity and sends these values via the LoRaWAN protocol. It can be used in many professional areas such as smart cities, building automation, food processing, etc.
The LHT52 is powered by 2 x AAA batteries and can last for several years. If the batteries are empty, they can simply be replaced

.
The LHT52 is compatible with the LoRaWAN v1.0.3 protocol and works with a standard LoRaWAN gateway.
The sensor has a data log function to ensure that sensor data is not lost. The sensor data for each uplink is stored and can be loaded from a LoRaWAN server via a downlink command.

If the temperature rises above a set value, the LHT52 can send alarm uplink packets at short time intervals.
