From $584.00Sale Price
DRAGINO NB-IoT 80 GHz Microwave Radar Distance Sensor | Solar Powered Available is an NB-IoT microwave radar sensor for non-contact distance measurement, liquid level monitoring and object detection. Its 80 GHz FMCW radar provides measurement ranges from 200 mm up to 3,000 mm, 12,000 mm or 25,000 mm, depending on the model, with 1 mm resolution and ±20 mm accuracy. The solar-powered MR-XX-NS combines a solar panel with a 3000 mAh Li-ion battery while MR-XX-NS is powered by 8500/19000 mAh Li/SOCl2 battery for long-term remote monitoring.

The DRAGINO NB-IoT 80 GHz Microwave Radar Distance Sensor | Solar Powered Available is designed for remote distance and level measurement where a wireless cellular connection is preferred. The sensor uses 80 GHz FMCW microwave radar, allowing it to measure the distance to different objects without requiring physical contact.

Microwave radar can be advantageous in environments where condensation or dust may affect other sensing technologies. Dragino specifically states that the radar can continue to detect distance correctly even when there is water or thick dust on top of the sensor.

The sensor is available with different measurement ranges. The 3 m version measures from 200 to 3,000 mm, the 12 m version from 200 to 12,000 mm, and the 25 m version from 200 to 25,000 mm.

How it works

  • The sensor uses 80 GHz FMCW microwave radar to detect the distance between the sensor and the target.
  • It performs non-contact distance measurement using the radar signal.
  • Measurement data can be transmitted through an NB-IoT cellular network.
  • The device supports TCP, MQTT, UDP, MQTTs and CoAP for different IoT communication requirements.
  • It can periodically send data to an IoT server.
  • Downlink communication can be used to change configuration settings.
  • Multiple radar samples can be taken before a single uplink transmission.
  • Bluetooth v5.1 is available for remote configuration and firmware updates.
  • The MR-XX-NS uses a solar panel and 3000 mAh Li-ion battery, while the MR-XX-NB uses an 8500/19000 mAh Li/SOCl2 battery.

Why choose this product?

  • 80 GHz radar sensing: Provides non-contact distance measurement using microwave radar.
  • Suitable for challenging environments: Dragino states that microwave radar is more reliable than ultrasonic or LiDAR in environments with condensation or dust.
  • Multiple measurement ranges: The 3 m, 12 m and 25 m options allow the sensor to be selected according to the required measuring distance.
  • NB-IoT connectivity: The sensor can communicate directly over supported NB-IoT cellular networks without requiring a local LoRaWAN gateway.
  • Solar-powered option: The MR-XX-NS combines a solar panel with a rechargeable 3000 mAh Li-ion battery for remote installations.
  • Flexible IoT communication: Support for TCP, MQTT, UDP, MQTTs and CoAP provides different options for connecting the sensor to IoT platforms.

Benefits

The radar-based measurement allows the sensor to monitor distances without making physical contact with the measured object. This makes the technology suitable for applications such as liquid level monitoring, object detection and distance measurement.
