LHT65 LoRaWAN Temperature & Humidity Sensor


The Dragino LHT65 Temperature & Humidity sensor is a Long Range LoRaWAN Sensor. It includes a built-in Sensirion SHT20 Temperature & Humidity sensor and has an external sensor connector. It comes in four variants with a choice of external sensors:

  • E1: DS18B20 Temperature Probe, 1m cable
  • E2: 3.5mm to 5 wire cable for Interrupt/ADC/Counting Sensor
  • E3: Flat DS18B20 Temperature Probe, 2m cable
  • E5: BH1750 Illumination Sensor
SKU: LHT65 Categories: , ,

Product Description

The LHT65 is a fully compliant LoRaWAN sensor, and allows users to send data over extremely long ranges. It provides ultra-long range spread spectrum communication and high interference immunity while minimizing power consumption. It targets professional wireless sensor network applications such as irrigation systems, smart metering, smart cities, and building automation.

The LHT65 has a built-in 2400mAh non-chargeable battery which can be used for more than 10 years*.

The LHT65 is fully compatible with the LoRaWAN v1.0.2 protocol, and it can work with a standard LoRaWAN gateway.

The LHT65 also has 3200 timestamped data records of internal storage which can be retrieved by timestamp for further analysis.
