DRAGINO LHT65S-EU868-NE117 Temperature & Humidity Sensor

overview

The Dragino LHT65S-NE117 temperature and humidity sensor is a long range LoRaWAN sensor. It has a built-in temperature and humidity sensor and has a connection for an external temperature sensor.

The LHT65S-NE117 enables users to send data and achieve extremely long ranges. It provides ultra-long range spread spectrum communication with high noise immunity and minimal power consumption. It is suitable for professional wireless sensor network applications such as irrigation systems, smart meters, smart cities, building automation, etc.

The LHT65S-NE117 external sensor uses the NIST-traceable TI TMP117A temperature sensor with an accuracy of 0.1°C in the normal temperature range.

The LHT65S-NE117 has a built-in non-rechargeable 2400mAh battery that can be used for up to 10 years*.

LHT65S-NE117 is fully compatible with LoRaWAN v1.0.3 Class A protocol, it can work with a standard LoRaWAN gateway.

LHT65S-NE117 supports datalog function. It will record the data when there is no network coverage, and users can retrieve the sensor value later to ensure no sensor value is lost.

*Actual battery life depends on how often data is sent.

The external antenna allows the sensor to achieve better coverage than the LHT65N-NE117.
