LoRaWAN Ultrasonic Distance/Range Sensor

LoRaWAN Ultrasonic Distance/Range Sensor


The LDDS75 is a LoRaWAN Distance / Range Sensor usable for a wide range of Internet of Things applications. It is used to measure the distance between the sensor and a flat object. The distance detection sensor is a module that uses ultrasonic sensing technology for distance measurement. Temperature compensation is performed internally to improve the reliability of the measured distance.

The LDDS75 can be used in scenarios such as horizontal distance measurement, liquid level measurement, parking management systems, object proximity and presence detection, intelligent trash can management systems annd many other IoT applications.

SKU: LDDS75 Categories: , ,

Product Description

The LDDS75 detects the distance between the sensor and the measured object and uplinks the value to any LoRaWAN IoT Server.

The LoRaWAN wireless technology used by the LDDS75 allows the sensor to send data over extremely long ranges. It provides ultra-long range spread spectrum communication and high interference immunity while minimizing power consumption. It targets professional wireless sensor network applications that require measuring distance, liquid levels, object presence, or any other range oriented application.

The LDDS75 is powered by a 4000mA Li-SOCI2 battery. It is designed for long term use up to 10 years*.

Each LDDS75 is pre-loaded with a set of unique keys for LoRaWAN registration. Register these keys to any LoRaWAN server and the sensor will auto connect after power on.

*Actual lifetime depends on network coverage, uplink interval, and other factors.
