Dragino DDS75 Ultrasonic Distance Sensor (LoRaWAN, NB-IoT & LTE-M)
The Dragino DDS75 Ultrasonic Distance Sensor is designed for non-contact distance and liquid level monitoring across LoRaWAN, NB-IoT, and LTE-M networks. It uses ultrasonic measurement technology to provide reliable readings in applications where physical contact with the measured surface is not suitable.
Suitable for Level and Distance Monitoring The DDS75 is commonly used for tank level monitoring, water and wastewater infrastructure, silo and bin monitoring, and industrial distance measurement applications. Its non-contact design helps reduce maintenance requirements and avoids issues associated with pressure-based or submerged sensors.
Multi-Network Connectivity The DDS75 platform is available in variants supporting LoRaWAN, NB-IoT, and LTE-M, allowing deployment on private LoRaWAN networks or carrier-operated cellular networks depending on coverage and site requirements.
Flexible Power Options Battery-powered and solar-powered variants are available, supporting long-term unattended operation in outdoor and remote environments.
Enhanced Functionality with Telemetry2U Integration When connected to the Telemetry2U IoT platform, the DDS75 supports dashboards, historical data logging, alerts, and device management, helping convert distance measurements into actionable monitoring outcomes.
