LDDS20 - Liquid Level Sensor

The Dragino LDDS20 consists of an ultrasonic liquid level sensor for measuring liquid levels. It uses a non-contact method to measure the height of liquid in a container without opening the container. The measured liquid levels are sent to a LoRaWAN® network for further analysis.

Features

• Ultrasonic non-contact liquid level measurement
• Valid measurement range: 20 mm - 2000 mm
• High accuracy: ±(5mm + S × 0.5%) where S is the measured value
• LoRaWAN connectivity for long-range wireless transmission
• Ultra-low power consumption
• Suitable for pure liquid without irregular deposition
• Compatible with non-metal materials less than 10 mm

Use Cases

• Water tank level monitoring
• Industrial liquid storage management
• Agricultural irrigation systems
• Wastewater treatment monitoring
• Chemical storage tank monitoring
• Remote liquid inventory management

Thinger.io Integration

The LDDS20 integrates with Thinger.io through a LoRaWAN network server, enabling real-time monitoring and data analysis of liquid level measurements.

Requirements

A LoRaWAN server is required to communicate the Dragino LDDS20 into Thinger.io, some options are:

• The Things Stack
• LORIOT
• ChirpStack

Alongside, the corresponding plugin for the selected LoRaWAN server needs to be installed in your Thinger.io instance.

Get Started

Installation

Look for the plugin in the Thinger.io Plugin Store and install it in your Thinger.io instance. Once the plugin is installed a new Product will be created for this device.

Configuration

The Product is already preconfigured, check that the auto provision prefix matches the one selected in your LoRaWAN server plugin in Thinger.io, or change it to your desire.

Usage

Start sending uplinks for autoprovisioning devices and buckets. This product also provides a predefined dashboard and downlinks.
