LoRaWAN Microwave Radar Distance Sensor
LoRaWAN Microwave Radar Distance Sensor (MRD Series)
The ioX-Connect MRD-Series Microwave Radar Distance Sensor uses 80 GHz radar technology to deliver high-precision, non-contact distance measurements in conditions that defeat ultrasonic and lidar sensors. Whether your application involves condensation, heavy moisture, dust, or solid obstructions like wood and plastic, this sensor reads through them all with ±20 mm accuracy and 1 mm resolution.
Available in three range models — MRD-03 (3 m / 9.8 ft), MRD-12 (12 m / 39.4 ft), and MRD-25 (25 m / 82.0 ft) — the MRD-Series connects over LoRaWAN for long-range, low-power wireless transmission, with NB-IoT and LTE variants also available. Pre-provisioned in the ioX-Connect platform, each sensor is ready to deliver real-time distance data to your dashboard within minutes of deployment.

It’s Not Just a Sensor, It’s a System
A standalone distance sensor gives you a number. The ioX-Connect MRD-Series gives you actionable intelligence. Every reading flow through the ioX-Connect platform where it is stored, analyzed, and transformed into alerts, trends, and operational insights that drive better decisions across your entire facility.
Because the MRD-Series is pre-provisioned in the ioX-Connect ecosystem, it works seamlessly with your existing LoRaWAN gateways, dashboard configurations, and alert rules. Add a distance sensor to a water treatment plant today, and it immediately inherits your existing notification workflows, user permissions, and reporting templates, no integration project required.

Water Level Monitoring in Tanks and Reservoirs
Municipal water utilities and industrial facilities use the MRD-Series to monitor water levels in storage tanks, reservoirs, and clearwells without contact probes that corrode or foul over time. The 80 GHz radar reads accurately through condensation and humidity that forms above warm water surfaces, delivering reliable level data in conditions that defeat ultrasonic sensors.
- Eliminate manual dipstick checks across distributed tank infrastructure
- Receive automated alerts when levels drop below refill thresholds or approach overflow
- Track historical fill patterns to optimize pumping schedules and reduce energy costs
- Monitor sewer flow levels in real time to detect blockages and overflow risks before they become emergencies
- Deploy across stormwater retention basins with solar-powered models for maintenance-free operation
- Integrate level alerts with municipal SCADA systems for automated pump control
Sewer and Stormwater Management
Sewer systems present some of the most challenging conditions for distance sensors: high humidity, condensation, corrosive gases, and unpredictable flow surges. The MRD-12 and MRD-25 models measure water distance in manholes, wet wells, and stormwater basins where ultrasonic sensors produce erratic readings due to moisture interference.
Smart Agriculture and Irrigation Management
Precision agriculture demands reliable water management data. The MRD-Series monitors irrigation reservoir levels, water tank fill status, and canal water heights across sprawling farm operations. Paired with ioX-Connect soil moisture sensors, facilities managers gain a complete picture of water supply and demand.
- Monitor irrigation reservoir levels remotely across thousands of acres
- Automate tank refill triggers when water drops below irrigation thresholds
- Combine distance data with soil moisture readings for precision water allocation
- Provide real-time parking availability data to drivers, reducing circling time and congestion
- Monitor loading dock occupancy to optimize delivery scheduling and throughput
- Track fleet vehicle presence in yards to verify dispatch status and asset utilization
- Optimize collection routes by servicing only bins that have reached fill thresholds, reducing fuel costs by up to 30%
- Prevent overflow and associated fines by triggering alerts when compactors approach capacity
- Track fill-rate patterns to right-size containers and adjust collection frequency by season
Parking and Vehicle Detection
The MRD-03 short-range model detects vehicle presence in parking structures, loading docks, and fleet yards. The narrow 7.6° beam angle ensures each sensor monitors a single parking space without cross-talk from adjacent spots, enabling accurate occupancy counts in covered and outdoor facilities.
Waste Management and Fill-Level Sensing
Waste haulers and facility managers deploy the MRD-Series inside dumpsters, compactors, and waste bins to monitor fill levels remotely. The radar penetrates dust and debris that block optical sensors, delivering accurate fill percentages that enable route optimization and prevent overflows.

The three models differ in maximum measurement range. The MRD-03 measures from 200 mm to 3,000 mm (7.9 in to 9.8 ft), the MRD-12 from 200 mm to 12,000 mm (7.9 in to 39.4 ft), and the MRD-25 from 200 mm to 25,000 mm (7.9 in to 82.0 ft). All three share the same 80 GHz radar technology, ±20 mm accuracy, and 1 mm resolution. Choose the model that matches your application’s maximum distance requirement.
The 80 GHz radar can penetrate certain non-metallic materials such as plastic and wood, so in some configurations it can measure through a tank lid made of these materials. However, metal enclosures will block the radar signal. For closed metal tanks, the sensor should be mounted inside the tank above the liquid surface, looking downward. Contact our team for application-specific guidance.
The MRD-Series supports BLE (Bluetooth Low Energy) configuration. Use a smartphone or tablet to connect wirelessly and adjust parameters such as measurement interval, alert thresholds, and LoRaWAN settings. Firmware updates are delivered wirelessly via OTA (Over-The-Air), so you never need to physically connect to the sensor for software updates.
LoRaWAN (Long Range Wide Area Network) is a low-power wireless protocol designed for IoT devices. It enables sensors to transmit small data packets over long distances (up to 10 km / 6 miles in open terrain) while consuming very little energy. LoRaWAN operates in unlicensed ISM bands (915 MHz in the US), which means no recurring cellular data fees for your sensor network.
LoRaWAN sensors typically achieve 2–5 km (1.2–3 miles) in urban environments with buildings and obstructions, and up to 10 km (6 miles) or more in open, rural areas. Actual range depends on antenna height, terrain, building density, and environmental conditions. ioX-Connect gateways are designed to maximize coverage for your specific deployment scenario.
LoRaWAN uses AES-128 encryption at two levels: a network session key that secures communication between the sensor and the network server, and an application session key that encrypts the actual data payload end-to-end. This dual-layer encryption ensures your distance measurement data is protected from interception and tampering throughout the entire transmission chain.
