Long-Range Non-Contact Distance & Level Monitoring

The ioX-Connect ULR75 Ultrasonic Range/Distance Sensor provides high-precision, non-contact measurement for industrial and smart city applications. Using ultrasonic sensing technology with built-in temperature compensation, it ensures reliable distance and level readings even in challenging conditions.

With a detection range of 280 mm to 7,500 mm and accuracy of ±(1 cm + 0.3% of distance), the ULR75 is ideal for horizontal distance measurement, tank and liquid level monitoring, parking systems, waste bin management, sewer and bottom-water level detection, object proximity, and automation control.

Data is transmitted securely over LoRaWAN® to an ioX-Connect gateway, then streamed to the ioX-Connect platform for real-time analysis, alarms, and reporting. The device supports Bluetooth v5.1 configuration, OTA firmware updates, and remote management, making deployment fast and user-friendly.

Built in a rugged IP66-rated enclosure and powered by a long-life 8500 mAh Li-SOCl₂ battery (up to 5 years operation), the ULR75 is engineered for long-term, maintenance-free deployments.

Please Note: These LoRaWAN sensors require LoRaWAN-based gateways to function. They are not compatible with our RF-based gateways. To ensure seamless integration and optimal performance, we recommend using our pre-provisioned gateways, which come ready to communicate with the ioX-Connect platform. If you have any questions about compatibility or need assistance in choosing the right gateway, please contact our support team. We also offer NB-IoT/LTE-M versions for applications requiring cellular connectivity.

Frequently Asked Questions about LoRaWAN Sensors

What is LoRaWAN and how does it differ from other wireless protocols?

LoRaWAN (Long Range Wide Area Network) is a low-power, long-range wireless protocol designed for IoT applications. It operates in sub-GHz bands to provide kilometers of coverage on a single battery charge, unlike Wi-Fi or Bluetooth which trade range for higher data rates. Check out ourWhat is LoRaWAN Guide.

What is a LoRaWAN network and how does it enable integration, monitoring, and management of LoRa devices from any manufacturer or network operator?

A LoRaWAN network is an open, standards-based infrastructure that allows wireless devices—regardless of brand, model, or network provider—to seamlessly connect, communicate, and transmit data over long distances. Built on widely adopted LoRa technology (supported by organizations like The LoRa Alliance® and hardware from companies such as ioX-Connect and MultiTech), a LoRaWAN network acts as the backbone for unified device management.

This interoperability means you can onboard and monitor LoRa-based sensors from different manufacturers on a single platform, no matter who makes the devices or provides the connectivity. With secure, bidirectional data flow, you gain centralized visibility, control, and real-time analytics for all connected devices—simplifying expansion and ensuring future-proof scalability across any facility or set of use cases.

How far can LoRaWAN sensors communicate?

In ideal rural environments, LoRaWAN sensors can reliably transmit data up to 10 km from the gateway. In urban or obstructed areas, you can expect several kilometers of range—enough to cover entire campuses or multi-building sites.

What are the advantages of using a pre-provisioned LoRaWAN gateway versus one that is not pre-provisioned?

pre-provisioned LoRaWAN gateway like those offered by ioX-Connect takes the heavy lifting out of deployment:

  • Out of the box, it’s ready to go—network configuration, security keys, and app integrations are already handled.
  • Sensors join seamlessly with zero manual pairing and instantly appear in your dashboard.
  • You bypass all the headache of linking the gateway to the network server and integrating that with your IoT platform—everything is connected from the start.

On the flip side, gateways that aren’t pre-provisioned require a fair bit of manual setup. Expect to:

  • Spend extra time configuring network details, authentication, and server connections.
  • Tackle every integration step yourself, with potential troubleshooting along the way.
  • Take on additional security configuration responsibilities to ensure safe device communications.

In short: pre-provisioned gateways dramatically accelerate setup, minimize IT effort, and let you focus on scaling your deployment rather than wrestling with infrastructure.

What is the battery life of a typical LoRaWAN sensor?

Thanks to ultra-low-power modulation, most LoRaWAN sensors last 5 years or more on a standard lithium battery, depending on reporting frequency and environmental conditions. For sensor specific battery life, check out our LoRaWAN hardware catalog.

What security measures are in place at the edge, including device identity, authentication and encryption in the LoRaWAN stack?

LoRaWAN uses AES-128 encryption at both the network (NwkSKey) and application (AppSKey) layers. Combined with ioX-Connect’s role-based access controls, this ensures end-to-end protection and prevents unauthorized data access.

How LoRaWAN Keeps Data Secure

The LoRaWAN security stack is built on top of LoRa modulation (PHY) and adds a robust security layer with unique device identity, authentication, and authorization for every sensor and gateway. Symmetric AES-128 keys—defined in the IEEE 802.15.4/2006 Annex B—are generated for each device. The Network Session Key (NwkSKey) encrypts network-related messages, while the Application Session Key (AppSKey) encrypts application-specific data, so only your application ever sees the payload.

Importantly, LoRaWAN gateways operate much like routers: they securely forward data between devices and the cloud using protocols such as DTLS, TLS, or VPN, but never decrypt or access your data or keys. This architecture ensures that your sensor data remains private and protected end to end, even as it travels across public or shared infrastructure.

Can I mix different manufacturers’ LoRaWAN devices on the same network?

Yes. LoRaWAN is an open standard, so you can deploy most LoRaWAN gateways and devices alongside other ioX-Connect certified sensors—our platform ensures seamless, zero-touch integration regardless of the vendor.Alternatively ioX-Connect offers our own range of affordable LoRaWAN Gateways and Devices. Please reach out to us at:sales@iox-connect.comto find out if the LoRaWAN devices you are considering is certified for use in our platform.

What types of applications are best suited for LoRaWAN sensors?

LoRaWAN excels in scenarios requiring wide-area coverage and infrequent small data packets, such as environmental monitoring (temperature, humidity, air quality),predictive maintenance(vibration, pressure), andasset trackinginagriculture,smart buildings, andindustrial settings.

How many sensors can a single LoRaWAN gateway support?

A single gateway can handle hundreds to thousands of sensors, depending on reporting intervals and network traffic. This star-of-stars architecture scales easily as you add endpoints. Reach out to our sales team at:sales@iox-connect.comif you need specifics or check out our range ofLoRaWAN Gateways.

Do LoRaWAN sensors require line-of-sight to the gateway?

No—LoRaWAN’s robust modulation penetrates walls and obstructions. While line-of-sight can maximize range, most indoor and urban deployments work reliably without it.
