More Detail

Overview

The Dragino LDDS20 is a LoRaWAN Ultrasonic liquid level sensor for Internet of Things solution. It uses non contact method to measure the height of liquid in a container without opening the container, and send the value via LoRaWAN network to IoT Server

The LDDS20 sensor is installed directly below the container to detect the height of the liquid level. User doesn’t need to open a hole on the container to be tested. The non contact measurement makes the measurement safety, easier and possible for some strict situation.  

 LDDS20 uses ultrasonic sensing technology for distance measurement. LDDS20 is of high accuracy to measure various liquid such as: toxic substances, strong acids, strong alkalis and various pure liquids in high-temperature and high-pressure airtight containers.

The LoRa wireless technology used in LDDS20 allows device to send data and reach extremely long ranges at low data-rates. It provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current consumption.



Features

  • LoRaWAN 1.0.3 Class A

  • Ultra low power consumption

  • Liquid Level Measurement by Ultrasonic technology

  • Measure through container, No need to contact Liquid.

  • Valid level range 20mm - 2000mm

  • Accuracy: ±(5mm+S*0.5%) (S: Measure Value)

  • Cable Length : 25cm

  • Bands: CN470/EU433/KR920/US915/EU868/AS923/AU915/IN865

  • AT Commands to change parameters

  • Uplink on periodically

  • Downlink to change configure

  • IP66 Waterproof Enclosure

  • 8500mAh Battery for long term use
