LHT65N E5 LoRaWAN Temperature and Humidity Sensor with Light Sensor

The LHT65 E5 temperature and humidity sensor from Dragino is a LoRaWAN sensor with an additional external light sensor that measures illuminance in lux. The module has an accurate SHT20 temperature and humidity sensor. The LHT65 has an integrated non-rechargeable 2400mAh battery, which depending on the number of transmissions, is sufficient for 10 years or more (see operating instructions for more details). The LHT65 is compatible with the LoRaWAN V 1.0.2 protocol and can be operated via a standard LoRaWAN gateway. The LHT65 has 3200 retrievable data records, which are stored with a timestamp.
