The LHT65 allows users to measure and send data, reaching ultra-long ranges via LoRaWAN networks. It provides spread spectrum communication and high interference immunity whilst minimising power consumption. It is a reliable and simple solution for critical temperature monitoring applications, including laboratory and hospital environments.
The LHT65 has a built-in 2400mAh non-chargeable battery with a lifespan of up to 10 years (depending on the transmit frequency). It includes an internal memory capable of storing 3200 data records with a date/time stamp that can be retrieved via the supplied programming cable (USB-TTL converter will be required and is sold separately). The LHT65 is pre-programmed to send records every 20 minutes, with capability to be customized to suit user needs. </p>
The LHT65 is calibrated and tested out of the factory. NATA calibration with a certificate of certification can be provided if required, making it perfect for critical monitoring applications. Please contact Telemetry2U for more information.
Telemetry2U has a live demo of a Dragino LHT65 Temperature/Humidity Sensor running on our IoT Platform.
