Dragino LHT65S NE117 LoRaWAN Temperature & Humidity Sensor (US915)
Features long-range spread spectrum communication
Equipped with internal and external temperature sensors
Supports Datalog feature for data retrieval
Powered by a 2400 mAh battery with up to 10 years lifespan
The Dragino LHT65S NE117 LoRaWAN Temperature & Humidity Sensor (US915) is a long-range sensor designed for a variety of professional wireless sensor network applications. This includes, but is not limited to, irrigation systems, smart metering, smart cities, and building automation.
The sensor is equipped with an internal temperature and humidity sensor, and also has the capacity to connect to an external temperature sensor via an external sensor connector. This feature allows for the transmission of data over extremely long distances. The sensor utilizes ultra-long range spread spectrum communication, ensuring high interference immunity while keeping current consumption to a minimum.
The external probe of the sensor employs a TI TMP117A NIST traceability temperature sensor, which boasts an accuracy of 0.1 °C in the normal temperature range. The sensor is powered by a built-in 2400 mAh non-chargeable battery, which can last up to 10 years. The sensor is fully compatible with the LoRaWAN v1.0.3 Class A protocol, and can function with a standard LoRaWAN gateway.
The sensor also supports a Datalog feature, which records data when there is no network coverage. This allows users to retrieve sensor values at a later time, ensuring that no sensor readings are missed. The sensor can be remotely configured via LoRaWAN Downlink and has a tri-color LED to indicate status.
The built-in temperature sensor has a resolution of 0.01 °C, an accuracy tolerance of ±0.3 °C, a long-term drift of < 0.02 °C/yr, and an operating range of -40 ~ 80 °C. The built-in humidity sensor has a resolution of 0.04 %RH, an accuracy tolerance of ±3 %RH, a long-term drift of < 0.02 °C/yr, and an operating range of 0 ~ 96 %RH. The external temperature sensor has an accuracy of ±0.1 °C (maximum) from -20 to 50 °C, ±0.2 °C (maximum) from -40 to 100 °C, and ±0.3 °C (maximum) from -55 to 150 °C.
If you are not satisfied for whatever reason with a Product you bought on the Site, it is possible to return it for refund within 30 days from the date you received it unless otherwise indicated in the Product listing. You must first advise the Vendor associated with your order in your account to obtain a return authorization (‘’RA’’) number before returning a Product.

The Product must then be returned in its original packaging (in perfect condition for resale) with its receipt and your (‘’RA’’) number. Reimbursement will be denied for any Products which do not conform to the above mentioned conditions.
Build-it-yourself Robot Parts are not refundable once assembled. Robots & Kits requiring assembly or soldering are also not refundable once assembled, soldered or modified in any way. All sales of robotic software and apps are final and cannot be refunded or exchanged. Returns are not accepted on special orders and clearance items except when they are found defective, in which case the Product may be repaired or replaced at the Vendor’s discretion. 20% Restocking fees may apply if you are returning a large quantity of the same Product that was ordered specifically for you from the manufacturer.
Please note that all items will be reimbursed within 7 to 14 days of receiving the Product (shipping fees excluded). You must also cover the cost of returning the Product. Shipping fees will only be refunded if the return is a result of a shipping error on our part. Cleaning fees of USD 100 may also be charged if a domestic robot is returned and has not been properly cleaned.
