The Dragino LHT65N-E31F temperature and humidity sensor is a long-range LoRaWAN sensor. It has a built-in temperature and humidity sensor as well as an external temperature and humidity sensor.
The LHT65N-E31F allows the user to send data and achieve extremely long ranges. It offers extremely long-range spread spectrum communication and high interference immunity with minimal power consumption. It is suitable for professional wireless sensor network applications such as irrigation systems, smart meters, smart cities, building automation, etc.
The LHT65N-E31F external probe uses Sensirion's SHT31F high-precision temperature and humidity sensor.
The LHT65N-E31F has a built-in 2400mAh non-rechargeable battery that can last up to 10 years*.
The LHT65N-E31F is fully compatible with the LoRaWAN v1.0.3 Class A protocol and can work with a standard LoRaWAN gateway.
LHT65N-E31F supports datalog function. It records the data when there is no network coverage and users can retrieve the sensor value later to ensure that no sensor value is lost.
*Actual battery life depends on how often data is sent.
