Wide Measuring Range: Measures air temperature from -40 to 80°C and humidity from 0 to 96%RH Low Power Consumption: 2400mAh battery lasts over 10 years Long-Range Transmission: Data coverage up to 3–5 km Multi-Platform Support: Compatible with Helium, TTN, and more Optional External Probe: Supports add-ons like surface temperature sensors Data Retrieval: Up to 178 historical records accessible via downlink command Alarm Function: Focuses on actionable data only Flexible Configuration: AT commands and LoRaWAN downlink for remote parameter setup Description LHT65N allows users to send data and reach extremely long ranges. It provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current consumption. It targets professional wireless sensor network applications such as irrigation systems, smart metering, smart cities, building automation, and so on. LHT65N has a built-in 2400mAh non-chargeable battery which can be used for more than 10 years. It is fully compatible with the LoRaWAN v1.0.2 protocol, it can work with the standard LoRaWAN gateway. Also, it has 3200 data records with datetime which can be retrieved with datetime for further analysis. Note LHT65N is mainly used for indoor environment monitoring. If you need a sensor that meets the industrial standards, you can choose SenseCAP S2101 LoRaWAN Air Temperature and Humidity Sensor, which can work from -40℃ to 80 ℃ and has IP66 rugged case to withstand exposure to an outdoor environment. S2101's built-in 19Ah battery can support up to 10 years of usage while built-in Bluetooth can enable 1 minutes integration to quickly get it started.
