DRAGINO LoRaWAN Ultrasonic Liquid Level Sensor with Solar Power Option

From $236.00Sale Price
DRAGINO LoRaWAN Ultrasonic Liquid Level Sensor with Solar Power Option is a LoRaWAN ultrasonic liquid level sensor designed to measure liquid height without direct contact with the liquid. Installed beneath a suitable container, it uses ultrasonic sensing to measure the distance through the container wall and sends the measurement to an IoT server via LoRaWAN. The sensor supports a 20 mm to 2000 mm measurement range, an accuracy of ±(5 mm + S × 0.5%), Bluetooth v5.1 configuration and wireless OTA firmware updates.

The DRAGINO LoRaWAN Ultrasonic Liquid Level Sensor with Solar Power Option is designed for remote monitoring of liquid levels in suitable tanks and containers. It uses ultrasonic technology to measure the distance to the liquid without direct contact, with the sensor installed on the underside of the container.

Because the sensor does not need to contact the liquid, Dragino states that the DDS20-LB/LS can be used for applications involving toxic substances, strong acids, strong alkalis and pure liquids, including liquids contained in high-temperature and high-pressure airtight containers. Suitability depends on the container construction and installation conditions specified by the manufacturer.

The sensor transmits measurements through a LoRaWAN network to an IoT server. It supports LoRaWAN 1.0.3 Class A, multiple regional frequency bands, Bluetooth v5.1 configuration and wireless OTA firmware updates.

How it works

  • The DDS20-LB/LS is installed directly underneath the container.
  • An ultrasonic sensor measures the distance between the sensor and the liquid surface through the container wall.
  • The measurement is converted into liquid level information.
  • The sensor transmits the data through LoRaWAN to an IoT server.
  • The default uplink interval is 20 minutes, according to Dragino's documentation.
  • The device operates in LoRaWAN OTAA Class A mode by default and uses pre-loaded OTAA keys to join a LoRaWAN network.
  • Bluetooth v5.1 and LoRaWAN remote configuration can be used to configure the device.
  • Wireless OTA firmware updates are supported.

Why choose this product?

  • Non-contact measurement: The sensor measures through the container wall rather than being immersed in the liquid.
  • No tank opening required: The manufacturer states that the installation does not require a hole to be made in the container.
  • Remote monitoring: Measurements can be transmitted over LoRaWAN to an IoT server.
  • Suitable for a range of liquids: Dragino specifies applications involving toxic substances, strong acids, strong alkalis and various pure liquids.
  • Two power configurations: Choose the battery-powered DDS20-LB or solar-powered DDS20-LS according to the installation requirements.
  • Remote configuration: Bluetooth and LoRaWAN configuration support simplifies setup and ongoing device management.

Benefits

The non-contact design can be useful where direct contact with the liquid is undesirable or where modifying the container is not practical.

LoRaWAN connectivity allows level information to be collected remotely, making the sensor suitable for distributed monitoring installations where running communication cables to each tank would be impractical.

For installations with suitable sunlight, the DDS20-LS provides solar charging with a 3000 mAh rechargeable Li-ion battery. The DDS20-LB instead uses an 8500 / 19000 mAh Li/SOCl2 battery.
