The Dragino LHT65N-E5 LoRaWAN Temperature, Humidity & Illuminance Sensor (US915) is a long-range sensor designed to measure temperature, humidity, and illuminance. It is equipped with an internal temperature and humidity sensor, as well as an external illuminance sensor. This device is capable of transmitting data over extensive distances, offering ultra-long-range spread spectrum communication and high interference immunity while maintaining minimal current consumption. It is particularly suitable for professional wireless sensor network applications, including irrigation systems, smart metering, smart cities, and building automation.

The device is powered by a built-in 2400 mAh non-rechargeable battery, designed to last for over a decade. It adheres to the LoRaWAN v1.0.3 Class A protocol, enabling it to function with a standard LoRaWAN gateway. The device’s features encompass LoRaWAN Class A protocol, a variety of frequency bands, AT commands for parameter modification, remote configuration of parameters via LoRaWAN Downlink, and firmware upgradability via the program port. It also includes a tri-color LED to indicate status.

The sensor can be utilized in a variety of applications, such as wireless alarm and security systems, home and building automation, automated meter reading, industrial monitoring and control, and long-range irrigation systems.

The built-in temperature sensor has a resolution of 0.01 °C, an accuracy tolerance of ±0.3 °C, and a long-term drift of less than 0.02 °C per year, with an operating range of -40 to 80 °C. The built-in humidity sensor has a resolution of 0.04 %RH, an accuracy tolerance of ±3 %RH, and a long-term drift of less than 0.02 °C per year, with an operating range of 0 to 96 %RH. The external illuminance sensor, based on the BH1750 Illumination Sensor, has a cable length of 50 cm, a resolution of 1 lx, a range of 0-65535 lx, and an operating range of -40 to 85 °C.
