The Dragino LHT65S-DS LoRaWAN Door Sensor (2400mAh / US915) is a sophisticated device designed for long-range communication in professional wireless sensor network applications. It integrates a temperature and humidity sensor along with a robust metal door sensor, enabling it to transmit data over extensive distances with high interference resistance while maintaining low power consumption. This makes it ideal for use in smart metering, smart cities, building automation, and irrigation systems.
The sensor operates on the LoRaWAN Class A protocol and is compatible with the US915 frequency band. It features a tri-color LED for status indication and supports remote configuration of parameters via LoRaWAN downlink. The device is equipped with a 2400mAh battery, offering a lifespan of up to 10 years, and allows for firmware upgrades through a program port.
The built-in temperature sensor provides precise readings with a high resolution and minimal long-term drift, while the humidity sensor offers reliable accuracy across a wide operating range. The external door sensor, constructed from aluminum alloy, detects door status changes effectively, enhancing the sensor's utility in various applications.
