LHT65: Temperature and Humidity Sensor

The LHT65 is a long range LoRaWAN node that includes a built-in SHT20 temperature & humidity sensor and allows for easy interface with various external sensors. Telemetry2U offer multiple pre-configured options. Including a 1 meter waterproof temperature sensor, a 2 meter temperature sensor with a flat cable (ideal for fridges or freezers), a light sensor or a cable to interface to custom sensors with either an interrupt, ADC or counting sensor output. The LHT65 device is fitted with a button that can be used for power on/off control or to reset the device. LHT65 also comes with an LED to indicate connection status.

SKU: T2U-LHT65-AU915 Category: Tag:

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.

 

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.
