From $273.00Sale Price
DRAGINO NB-IoT Ultrasonic Liquid Level Sensor with Solar Power Option is an NB-IoT distance detection sensor that uses ultrasonic technology to measure the distance between the sensor and a flat object. It provides a measurement range of 30 mm to 4500 mm with an accuracy of ±(1 cm + S × 0.3%), where S is the measured distance. Built-in temperature compensation helps improve measurement reliability. The sensor can transmit measurements to IoT platforms through NB-IoT and supports MQTT, MQTTs, UDP and TCP communication methods.

The DRAGINO NB-IoT Ultrasonic Liquid Level Sensor with Solar Power Option is designed for remote measurement of the distance between the sensor and a flat object. It uses ultrasonic sensing technology and incorporates internal temperature compensation to improve the reliability of the measured data.

With a specified measurement range of 30 mm to 4500 mm, the DRAGINO NB-IoT Ultrasonic Liquid Level Sensor with Solar Power Option can be used for both general distance detection and applications where the distance from a sensor to a surface represents a useful measurement, such as liquid level monitoring.

The sensor transmits its measurements to an IoT platform using an NB-IoT network. Dragino specifies support for MQTT, MQTTs, UDP and TCP, allowing the sensor to work with different IoT server requirements.

The DDS45-NB is powered by an 8500/19000 mAh Li/SOCI2 non-rechargeable battery  while DDS45-NS is powered by Solar panel + 3000mAh Li-ion battery and is designed by Dragino for long-term use. It also provides BLE configuration and OTA firmware updates for device management.

How it works

  • The ultrasonic sensor emits a signal towards the target object.
  • The sensor measures the distance between itself and the object.
  • Internal temperature compensation is used to improve measurement reliability.
  • The measured distance can be transmitted to an IoT platform through an NB-IoT network.
  • Multiple measurements can be sampled before a single uplink transmission.
  • Data can be sent periodically according to the configured operating parameters.
  • Downlink communication can be used to change configuration settings.
  • BLE can be used for device configuration and firmware updates.
  • An optional built-in SIM card and pre-configured IoT server connection are available for the specified version.

Why choose this product?

  • NB-IoT connectivity: Provides cellular IoT communication for remote installations without requiring a local LoRaWAN gateway.
  • Ultrasonic measurement: Measures distance without requiring physical contact with the target surface.
  • Wide measurement range: The specified range extends from 30 mm to 4500 mm for flat objects.
  • Remote data transmission: Measurements can be sent to an IoT platform using several supported communication protocols.
  • Remote configuration: BLE and OTA support make configuration and firmware maintenance more convenient.
  • Outdoor-ready enclosure: The IP66 enclosure provides protection for applications where water and dust resistance are required.

Benefits

It can reduce the need for manual distance checks by allowing measurements to be collected and transmitted remotely.

Its non-contact ultrasonic measurement is useful where the sensor needs to monitor a surface, liquid level or object without physically touching it.

The combination of NB-IoT communication and long-term battery operation also makes it practical for distributed monitoring points where wired communications are inconvenient.
