LDDS75 LoRaWAN Distance Detection Sensor

Based on the LSN50 Open Source platform, The waterproof (IP68) LDDS75 offers long range connections to LoRaWAN networks. The LDDS75 uses ultrasonic sensing to measures distances between 280-7500mm (in typical conditions, around 25C, 65%). Temperature compensation is performed internally to improve the reliability of data. The LDDS75 can be applied to scenarios such as horizontal distance measurement, liquid level measurement, object proximity and presence detection, automatic control etc. Great for keeping an eye on your rain water tanks.


Please note that all LoRaWAN IoT Sensor nodes supplied by Telemetry2U will work with 3rd party network/application servers, like TTN, but if you would like to use your sensors on Telemetry2U’s advanced, plug-and-play IoT Platform, then you will need to purchase a license by selecting from the drop-down box below. Products purchased with a license will be shipped with the latest firmware and configuration optimised for T2U, with no programming or set-up required.

The LDDS01 is based on the LSN50 platform, a long range LoRaWAN node that provides spread spectrum communication and high interference immunity whilst minimising power consumption. Its IP68 waterproof design makes it suitable for outdoor use and its powered by a 4000mA Li/SOCl2 non-rechargeable battery. Due to its low power operation, users can expect years of operation with a moderate logging rate. 

The Ultrasonic distance sensor comes pre-fitted on the LSE01 and by default, the data record containing the battery voltage and the object distance (in mm) is sent every 20 minutes.

Features:The operating parameters and many other settings on the LSN50 can be modified via AT commands on the serial port interface, but an FT232RL USB-TTL converter is required for this task (not supplied).  The communications port can also be used to upload new firmware via the built-in bootloader.  Some settings can also be changed via the server, like the transmit interval, operating mode, confimration mode and the reset command.
