SensNode-NB-RDR NB-IoT Microwave Radar Distance Detection Sensor

SensNode-NB-RDR is an NB-IoT microwave radar distance detection sensor used for IoT solutions. It uses 24GHz microwave to detect the distance between different objects. Unlike ultrasonic or Lidar measurement, microwave radar is more reliable in humid/dusty environments. It can accurately detect the distance even if there is water or thick dust on the sensor.

SensNode-NB-RDR can be applied to scenarios such as horizontal distance measurement, parking management systems, object proximity and asset detection, smart trash can management systems, robotic obstacle detection, automatic control, and sewage. The device can measure two distances: the nearest object and the next object behind the nearest one.

SensNode-NB-RDR has an alarm feature that allows the device to send data at short intervals when the target distance goes outside the configured range.

SensNode-NB-RDR supports various uploading methods including MQTT, MQTTs, UDP, TCP, and COAP for different application requirements, allowing data to be uploaded to various IoT servers.

SensNode-NB-RDR supports configuration and OTA updates via BLE, making it user-friendly. It operates with an 8500 mAh Li-SOCI2 battery and is designed for long-term use lasting for years.

WARNING: Ensure that there is NB-IoT coverage in the area to be used!
