Features

Built-in Temperature & Humidity Sensor

LHT52 comes with a built-in sensor to measure and monitor temperature and humidity levels.

Battery-Powered

The LHT52, powered by two AAA batteries, designed for long-term use up to several years.

Datalog Feature

The sensor supports a Datalog feature that records sensor values for every uplink transmission, ensuring that no data is missed. A LoRaWAN server through a downlink command can retrieve this recorded data

Temperature Alarm

The LHT52 has a temperature alarm feature that enables it to send alarms at regular intervals if the temperature exceeds preset limits.

Firmware Update

Allows for easy installation of new firmware on the device.
